    Palpation has been used for centuries in medicine as a screening and diagnosis modality for a number of pathological conditions. However, this technique is subjective since palpation sensitivity depends on the skill and experience of a medical examiner. An objective approach to acquire quantitative tactile information is needed. A roller scanning type palpation sensor system consisting of an x-axis linear slider and a palpation probe for detecting lumps in a soft object such as the prostate tissue is proposed and fabricated in this study. By translating the slider and changing the palpation angle of the probe, a chrome steel ball which was the contact component indented and scanned the surface of soft silicone phantoms embedded with hard lumps. Lumps were detected by measuring reaction force waveform fluctuations. Fundamental characteristics of the proposed sensor system were validated by comparison with the ground truth load cell output and showed a strong linear correlation with r2=0.9985. On silicone samples with hard lumps, the system was able to detect lumps of various sizes embedded at the depth of 5mm. From the results, the proposed sensor system holds potential for tissue characterization.

    BACKGROUND: Prostate Cancer screening based on manual palpation is subjective. Robotic palpation systems can objectively acquire stiffness conditions of the prostate. METHODS: A 2DoF cable driven robotic system for prostate palpation is proposed. An indirect method to estimate the contact force based on cable tension observation is presented. Kinematic models and a joint angle estimation method to determine the tip position of the probe are derived. Positioning accuracy was verified using an optical marker tracking system and by displacement measurement, respectively. The contact force estimation method was validated on silicone phantom samples. RESULTS: A good consistence between the estimated and measured contact force was observed. The contact force was correlated with the elastic modulus of each silicone phantom. There was also a good agreement between the theoretical and the measured tip position. CONCLUSION: In the proposed palpation system, the indirect contact force estimation method is viable and holds potential for the stiffness assessment of the prostate. The tip position vital for palpation can be determined through estimated joint angles.

    Palpation is a clinical diagnosis method utilized by physicians to acquire valuable information about the pathological condition of an organ using the sense of touch. This method, however, is subjective. The accuracy depends on the physician's experience and skill. Therefore, to make palpation objective and minimize variability in prostate cancer diagnosis among physicians, an automated palpation system is required. This paper describes the design and experimental evaluation of a 2 Degrees of Freedom (2DoF) tendon driven robotic palpation probe. The probe's palpation motion is controlled by actuating driving tendons using a cable-differential pulley transmission system and a return spring. A kinematic model of the robotic probe was derived. Furthermore, a tendon path length model was geometrically determined, and an optimization method for guide arc center placement to minimize change in tendon length was presented. Preliminary experimental and theoretical results were compared to determine the positioning accuracy. The difference between theoretical pitch angles [0°,80°] and measured values for the yaw angle range of [0°, 40°] was found to be in the range of 0.03° ~ 5.06°.Clinical Relevance- Diagnosis based on manual palpation is often subjective and palpation sensitivity depends on the physician's level of experience and skill. Therefore, an objective method for acquiring tactile information is relevant. Robotic palpation system provides objective and quantitative information for better understanding of the pathological and physiological changes in the tissue using mechanical properties as biomarkers.

    In this study, we focus on the tactile illusion of stiffness feeling by surface roughness. Human factors on tactile illusion is analyzed from the viewpoint of the fingertip stiffness and finger motion. Specifically, five types of samples with different surface roughness are fabricated. Sensory evaluations for the stiffness feeling and the roughness feeling are conducted. Also, the fingertip stiffness and fingertip force when the panelists touch the samples are measured. As a result, it is confirmed that tactile illusion on stiffness due to surface roughness occurs to some panelists. And it is shown that the tactile illusion is less likely to occur in panelists with hard fingertips. Moreover, the panelists with tactile illusion are classified into two groups based on the relationship between the surface roughness and the stiffness feeling. And it is suggested that each group has characteristics in the relationship between the touch motion and fingertip stiffness.

    <p>We focus on the hardness measurement by using a sensor unit arranging 8 piezoelectric elements in series. In previous study, it confirmed that the sensor unit is available to evaluate roughness on the sample. In the study, four silicone samples with different Young's modulus were prepared. In experiments, the sensor unit was placed on the sample and moved up and down with 1Hz. And the oscillatory waveform form each piezoelectric element was obtained. In analysis, the first peak voltage in the waveform were extracted and compared with the Young's modulus of the sample. From the results, it was found that the peak voltage related on Young's modulus. It was suggested that the sensor unit is available to evaluate the hardness of objects.</p>

    In this paper, palpation motions for prostate gland were measured using prostate examination simulator and motion capture system in order to evaluate the motion. In the measurements, six prostate models were prepared as palpation samples. While subjects diagnose the presence of lumps in prostate models and the size of prostate, fingertip position and force applying on prostate models were measured. From the results, it was confirmed that the expert diagnosed the state of prostate glands more accurately. By comparison of motion characteristics between the expert and beginners, the motion characteristics of experts were extracted.

    Itch is an unpleasant sensation associated with various disease, and can trigger scratching. Management of itch and scratching is important for treatment of disease. Therefore, quantitative and objective evaluation of itch and scratching is demanded. This work aims to develop the sensor system for evaluating the scratching motion. For the purpose, we focus on scratch sounds induced by scratching motion and, propose a nail mounted sensor system . In the sensor system a small microphone is attached on a nail for measuring scratching sounds. First, for investigating the relationship between the scratch sounds and the mechanical characteristics of human scratch motion, the artificial skin model made of polyurethane was used as a scratched object. The measurement system that can measure force and a motion of fingertip during scratching was constructed. Using the measurement system, various kinds of human scratch motions and sounds were measured. By signal processing of the scratch sounds, the several sound features were calculated and characteristics of scratch motions were extracted. Then, correlation coefficients between sound features and scratch motion properties were calculated. From the results, two pairs of the parameters were found as the most adequate parameter pair to evaluate the mechanical characteristics of human scratch motion. And using these parameters, "scratch evaluation map" was proposed as a method to evaluate the mechanical characteristics of human scratch motion. From the results, it was found that the developed sensor system has possibility to evaluate the mechanical characteristics of human scratch motion by the scratch sounds.

    Physician palpation is a useful medical examination, because it is non-invasive, quick and simple. However, to make an accurate diagnosis using palpation, physicians need long-time training and practice. Moreover, it is difficult for beginners to learn how to make a motion on palpation and what to feel at that time. Therefore, this study aims to clarify the relationship between the palpation motions and haptic sense, and to support beginners to improve the palpation skill. At first, models for palpation are designed. Each model has a hard lump made of silicone in soft polyurethane resin. The models are of seven types. The difference among them is the forms of lumps. Next, a measurement system for palpation motion is developed. The system has two cameras and a load cell. Subjects explore the models like conducting palpation, and then answer the lump forms. In experiments, palpation motion data of ten subjects are obtained by using the measurement system. The characteristics of the motion were extracted from the experiment data. And, it is confirmed that the instruction for the effective motions improves palpation skill.

    In recent years, aging of population is more and more progressing. The number of people who is bedridden is increasing because muscle strength and muscle mass decrease as people age. Therefore, rehabilitation and training are needed for independent lives. In order to improve their safety and efficiency, it is important to measure the state of muscle activity and muscle fatigue. Mechanomyogram (MMG) is one of the invasive method to evaluate a state of muscle. In addition, measuring surrounding muscles simultaneously is necessary to evaluate effects of rehabilitation and training because motions are performed by some muscles. Therefore, in this study, the state of crural muscles in isometric contraction was measured by multipoint MMG. Four sensors were taped on medial head of gastrocnemius muscle, lateral head of gastrocnemius muscle, tibialis anterior and the shinbone. Root mean squares and power spectral densities (PSD) were calculated from MMG signal to measure muscle activity. By comparing PSDs from four sensors, there are different frequency components in PSD from medial head from that from lateral head. From the results, it was found that the multiple MMG measurement is available to estimate the whole muscle activity during exercise.

    Palpation is a simple diagnosis method that doctors examine body and organs of patients by feeling with their hand. However, palpation is not objective because the palpation sensitivity depends on skill and experience of doctors. Therefore, an objective method for measuring tactile information is required. In related studies, the tactile sensor which can measure the size, the hardness and the position of a tumor is proposed. However, there is no system that can measure the mobility of a tumor which is fundamental information in a diagnosis by palpation. In this study, a palpation sensor system for evaluating the mobility of a tumor is fabricated. In measurement, the sensor measures the reaction force from the measuring object, while the sensor scans on the object. In reference to the motion of the doctor's hand during palpation, the sensor reciprocates above the tumor. By the reciprocating scanning, the waveforms with two peaks are obtained in the sensor output. Compared the time gap between the two peaks with the displacement of the tumor, it is found that the time gap is strongly related to the displacement. From the results, it is confirmed that the sensor is available to evaluate the mobility of a tumor.

    This paper describes a development of a measurement system for monitoring muscle activities of gastrocnemius muscle using a mechanomyogram (MMG) sensor. The measurement system is composed of MMG sensor, load cell and monitoring display. In MMG measurement of gastrocnemius muscle, the subjects sit on the measurement system in the long sitting position and perform a leg isometric constraction against a footboard with load cell. In experiment, for stable and reproducible measurement, proper footboard angle and proper force stepping on the footboard are investigated. First, to decide proper footboard angle, MMG measurement are carried out under conditions with three kind of footboard angle. Next, to decide proper exerting force, MMG measurement are carried out under conditions with three kind of force. As a result, it is found that the MMG measurement can be carried out stably and reproducibly under conditions that footboard angle is π/9[rad], and force is 7[%] of maximum voluntary contraction.

    In this paper, a sensor system for evaluating tactile feelings of scalp hair is developed. A sensor with concentric circles shape projection which imitates fingerprint was mounted on a beam that was fixed to a linear slider. A Polyvinylidene Fluoride (PVDF) film was used as a sensory part. The sensor output was obtained by contacting with the measuring object and scanning on it. Three parameters that are expected to have correlations with tactile feelings were calculated by signal processing of sensor outputs. Evaluation of human hair has problems due to randomicity and difficulty of putting them uniformly without overlapping. Therefore, a plate imitating the physical and chemical properties of human hair surface was used as measuring objects for stable measurement. The plates cleaned down with several kinds of treatment were measured by the sensor and human sense. By comparison between sensor outputs and sensory evaluation, it is confirmed that the sensor system can discriminate the treatment effects. The results suggest that these factors could be evaluated by the sensor system.

    This paper describes a characteristic evaluation of a solid polymer electrolyte (SPE) sensor. The sensor has a basic structure that the SPE film is sandwiched between thin carbon films. Each carbon is coated with Ag paste and they are covered with polymer films. SPE film has a good flexibility, and can be used in air. The SPE sensor output is related to the average of the curvature of the measured surface. In this paper, in order to obtain the output characteristics of the SPE sensor, the influence of the area size of the sensor element on the sensor output is investigated. As a result, it is found that the output is independent of the area size of the sensor element.

    This paper is concerned with a identification method of the Braille special characters using Braille sensor system. The compact Braille sensor using a PVDF (Polyvinylidene Fluoride) film is developed. The sensor output is measured with the sensor grasped with left hand moving over Braille manually. The Braille character is recognized by the obtained waveform. Then the recognized character is informed to user by voice. Braille of Japanese syllabary characters, for example 'ga', 'gi', 'gu', 'ge' and 'ge', are expressed by combining a special character, which represents sound type, and a normal character, which represents 46 Japanese syllabary characters, for example ka', ki', "ku', ke' and ko'. The signal processing for identification of normal and special Braille characters is proposed. The proposed method is examined experimentally. The obtained results show that the identification method is effective to recognize the special character of Braille.

    This paper describes an investigation of fundamental characterization of a contact stimulus by diapers. Contact stimulus is a kind of mechanical stimulus like contact force or friction. A sensor for measuring the contact stimulus is fabricated. The polyvinylidene fluoride (PVDF) film, which is a kind of piezoelectric material, and a strain gauge are used as the sensor parts. In order to investigate relationship between the contact stimulus and the sensor outputs, a machine which can give rise to the contact stimulus between the sensor and diapers by rotating the sensor is developed. By using this machine, friction between the sensor and a diaper is measured. A parameter calculated from the PVDF film outputs is proposed for evaluating friction. It was confirmed that there is a possibility to evaluate friction of diaper aginst the sensor by the proposed parameter.

    In this paper, a nail mounted palpation sensor is developed in order to perform a palpation by hand and stiffness measurement by a sensor simultaneously. The polyvinydene fluoride (PVDF) film. which is a kind of piezoelectric materials, is used as the sensor material. The sensor consists of a PVDF film, silicone sheet and a false nail. PVDF film was glued to silicone sheet, and is attached on artificial nail. The whole sensor part is fitted to finger nail with double-sided tape. In measurement, the finger is vibrated by a vibro-machine fitted to the root of the finger and the sensor output is obtained by contacting the finger tip on the objects. The fundamental characteristic and possibility of stiffness measurement are investigated using the silicone rubber samples with Young's modulus corresponding to prostatic cancer and normal prostate. The experimental results showed that magnitude of output voltage is corresponded with the stiffness of sample. It is confirmed that the nail mounted palpation sensor is possible to discriminate the stiffness by experiments.

    In this study, a mechanomyogram (MMG) sensor system for monitoring muscle conditions is developed. The polyvinylidene fluoride (PVDF) film is used as the sensory receptor of the MMG sensor. The sensor performance is verified by the fundamental experiment. The results show that the mean power frequency (MPF) of the sensor output is related to firing rate of action potential (AP) of muscle and the variance of the sensor output is related to the activity of fast fibers and complete recruitment. Next, muscle activities of isometric contraction are studied using the developed MMG sensor before and after muscle fatigue. Measurements were conducted on biceps and triceps brachii of healthy subjects with load. Experimental results show that contraction of fast fibers is occurred earlier and fast fibers activity increase earlier due to muscle fatigue. Focusing on the time shift of local maximum point in MPF and decrease of growth rate in variance, parameters for evaluation of muscle fatigue degree are proposed.

    This report focuses on a development of a 3-dimensional drag sensor. Three strain gauges and a nonmetal cylinder material constitute the sensor. The strain gauges are put on the side of the cylindrical material at intervals of 2π/3 radians. The strain gauges detect the deformation of the cylindrical material. In this report, we discuss the difference of the results caused by the difference of the position of the strain gauges put on the cylinder material. Moreover, the effectiveness of the sensor is examined through some experiments using the soft materials as the contact objects.

    This paper is a study on the development of active haptic sensor system for monitoring human hair under dry and wet conditions. The polyvinydene fluoride (PVDF) film, which is a kind of piezoelectric materials, is used as the sensory receptor. The sensor consist of a silicone rubber, a PVDF film, and a projection for the contact to objects. The sensor output is obtained by contacting and scanning of the sensor on the object. Evaluation using human hairs has problems due to randomicity, and difficulty of putting them uniformly without overlapping. Therefore, in this research panels imitating the physical and chemical properties of human hair are fabricated and used as measuring objects. By comparison between the sensor output and human sensory evaluation of the panels, it is confirmed that this sensor system is available for monitoring hair by both dry and wet condition.

    Human skin, which mainly consists of epidermis, dermis and hypodermis, is the largest organ of a human body. It has a lot of roles, for example, protection function , moisture maintenance function and sensory function. Moreover, it becomes a parameter that shows the health condition and beauty, because the skin is the outermost layer of a human body. Therefore, the development of the sensor that can measure the skin conditions in various parts of the body is demanded. However, sensors that had been developed before can measure limited parts of body or can measure only in limited condition. In this paper, the sensor that can measure various parts of human body in various conditions is developed and evaluated by measurement of the artifical skins that have various roughness.

    We have focused on human tactile function and developed tactile sensors and devices harmonized with human tactile sensations. First, an active sensing system for measuring tactile sensations is presented. Various tactile sensations are measured by the tactile sensor using the PVDF film. Then, a finger-mounted tactile sensor for detecting surface irregularity is presented. The human operator can easily detect the surface irregularity through the same motion as heretofore. Furthermore, a novel tactile device considering nail function is presented. This device deforms the nail and has a potential to change tactile sensitivity (enhance, decline, etc). The principle of this device is simple and it dose not intercept direct contact between the finger and the object.

    Activities of the skeletal muscles produce body movement, maintain body postures and position as well as support soft tissues. Monitoring the muscle activities is very important in rehabilitation, physical training, and in the development of life-support equipment for physically disabled persons. Myodynamometer and electromyogram (EMG) have been widely used for monitoring muscle activities. However, these methods monitor the contraction of the muscle indirectly. Recently, mechanomyogram (MMG) has attracted much attention for its ability to directly monitor the muscle contraction. The MMG is a recording of the mechanical vibration on the body surface caused by the dimensional change of the muscle fibers, and thus directly reflects the contraction of the muscle. Using of the MMG, it is expected that more detailed information of muscle activities such as muscle fatigue, which is difficult to be monitored by myodynamometer and EMG, can be obtained, as well as information of the activities of slow and fast fibers. However, current MMG sensors are only suitable for monitoring the isometric contraction of muscle, thus current studies using MMG mainly focus on the monitoring of the isometric contraction of muscle, for example, muscle fatigue estimation. Study of the MMG on the monitoring of non-isometric contraction of muscle has not yet thoroughly been done. In this thesis, a novel MMG sensor system that can be used for monitoring both the isometric and non-isometric contraction of muscle is developed.

    This Paper is a study on the development of an active palpation sensor that is wearable on a doctor's finger and can compensate the force to press against prostate for detecting prostate cancer and hypertrophy. The receptor of the sensor is a polyvinylidene fluoride (PVDF) film. A strain gauge that is used to detect the force is attached to a metal base. This sensor section is set in a finger stall in order to take stable contact between a user's finger and the sensor. The sensor is pressed against the prostate gland and driven sinusoidally with a constant amplitude vibration. For convenience, the structure is made up of two parts: sensor and vibro-machine. The sensor is worn on a doctor's finger tip and a vibro-machine is fixed at his finger root. With this structure, the doctor can move his finger freely. The results showed that the output of the sensor varies with the stiffness of prostate glands and the sensor is effective in diagnosing the condition of prostate glands.

    This paper reports a study on the development of an artificial rectum valve system using the SMA actuator. An artificial rectum valve was developed. A transcutaneous energy transmission system that provides energy for the SMA actuator implanted inside the body from outside the body was also proposed. Furthermore, to prevent the overheating of the SMA actuator, a closed loop temperature controller was developed and introduced into the transcutaneous energy transmission system. Finally to verify the function of the artificial rectum valve as an anal sphincter, in vivo animal experiments were conducted using dogs. The experiments verify that this valve works well as an artificial rectum valve.

    This paper is a study on the optimum design of a palpation sensor for detecting prostate cancer and hypertrophy. The receptor of the sensor is a polyvinylidene fluoride (PVDF) film placed on the surface of a matrix rubber base. The sensor is pressed against the prostate gland and driven sinusoidally, with a constant amplitude. The voltage signal from the PVDF film is integrated over the sampling period and is used as the output of the sensor for evaluating the stiflhess of the pressed prostate gland. The output strength of the sensor is dependent on the relative stiffness of the sensor base rubber to the stiffness of the object prostate gland Thus, the stiffness of the base rubber is of great importance to make the sensor output maximum and achieve the best discrimination of the normality and abnormality of the organ. The FEM analysis is introduced for the optimal design of sensor.

    This paper is concerned with the active tactile sensing using an artificial two-finger system together with the evaluation of human tactile sensation using the system. First, the samples such as newspaper, superfine paper, tracing paper, paper towel and toilet paper are pinched and/or stroked by the thumb and the forefinger of the volunteers, and their feelings of softness and roughness are obtained and classified with the use of the questionnaire. Next, the same samples are pressed and slid by the PVDF tactile sensor mounted on an artificial robotic two-finger system and the output signals from the sensor are collected and stored. Features on the collected data are then extracted by introducing the wavelet analysis and calculating the variance. They are compared with the evaluation of human fingers. Results of comparison show that the active tactile sensing using the artificial finger system well evaluates and describes the human tactile sensation.

    This paper is a study on the development of a sensor for detecting the catheter contact conditions. The sensor is composed of synthetic rubber layers and three strain gauges. The sensor is 12mm across and 15mm in length and mounted on the end of the catheter. The equation relating the sensor output with the contact conditions is formulated by using the three gauge output. The obtained results show the good correspondence of the estimated information with the initial applied condition.

    This paper is concerned with the development of an artificial urethral valve for treating urinary incontinence, which is driven by shape memory alloy actuators. Three types of valves are assembled and their opening and closing functions are examined experimentally by using the urethrae of male dogs. The latest model is driven by the non-contact induction heating system using power transmission coils. It is found that all of them show good opening and closing functions. The energy to drive the valve is transmitted by using an implanted coil of which outside diameter is 60 mm.

    This paper is concerned with the development of an artificial urethral valve for treating urinary incontinence, which is driven by shape memory alloy actuators. Two types of valves, one with handdrum form and the other with cylindrical configuration, are assembled and their opening and closing functions are examined experimentally by using the urethrae of male dogs. It is found that the cylindrical is better than the hand-drum form from the point of contact pressure with the urethra. A metallographical-mechanical model of the SMA plate is constructed and applied to the analysis of opening/closing functions of the valve. It is shown that the presented model well describes the motor functions of the artificial urethral valve.

    In this paper, a palpation sensor system to detect lumps in soft palpation objects such as breast cancer is developed. During scanning of the developed sensor on the measuring objects, the reaction force applied to the contact part is measured by a load cell. And the lump is detected by find a peak waveform of the reaction force. Measuring objects embedding a lump with several conditions of depth and diameter are prepared. Palpation experiments for the measuring objects are conducted. And from the results, it was found the lump of 6mm in diameter embedded in 15mm in depth can be detected with the developed palpation sensor system. In addition, by investigation of relationships between the pressing depth of the sensor to measuring objects and the depth of the detected lump, it was suggested that the depth of lump can be estimated from the combination of results for different pressing depth conditions.

    In this study, a single joint robot finger system to palpate the prostate is developed. For the palpation, the robot finger is bended by pulling the driving wires. And estimation of the robot fingertip position from the length of the driving wires and estimation of the contact force between fingertip and measuring objects are necessary. First, the theoretical model of the robot finger geometrically was constructed, and the relationship between the bending shape and the coordinates of the fingertip was derived. Also, a method to estimate the contact force between the fingertip and the object using the principle of virtual work from the tension of the driving wires was derived. Next, the robot fingertip position accuracy was confirmed by conducting position measurement experiment. Finally, a palpation experiment was conducted on the gel samples, and the utility of this system was confirmed by estimating the contact force.

    In this paper, method to estimate fingertip force with ring-type wearable sensor is proposed. To select effective exercises, it is important to accurately measure motion of patient, such as postures and force. Especially, fingers perform complicated movements, loss of function significantly adverse effects on active of living. Measurement of fingertip force is relatively difficult, because it is necessary to use load cells in the target object or between finger and object. Therefore, in previous study, we focused on the relationship between tension of tendon and fingertip force, and proposed ring-type wearable sensor to estimate the fingertip force. First, we investigate the relationship between finger joint angle and sensor output at the condition that the fingertip force is zero. Next, the relationship at the condition that fingertip force is applied is investigated too. Finally, on the basis of above investigations, the relational expression between the joint angle, the ring-type sensor output, and the fingertip force was derived as new calibration formula for estimating fingertip force.

    Human beings gain a lot of sense by using haptic perception. Especially, the sense of hardness is important for physician to palpate patients&amp;rsquo; bodies. However, it is difficult to share the sense of hardness. Therefore haptic hardness sensor systems are demanded. For the development of the haptic sensor system, it is necessary to elucidate the mechanism of human perception about the sense of hardness. In previous studies, it has been clarified that not only physical property about objects such as young&amp;rsquo;s modulus but also contact state such as contact area affects the sense of hardness. Therefore, this study aims to measure contact state of finger-tip during evaluating hardness for flexible objects. For this purpose, measurement system using Optical Coherence Tomography was developed. And contact area and three-dimensional contact shape during evaluating hardness for flexible objects were measured.

    In recent years, the information terminal using a touch panel has become widespread. Touch panel is a device that people touches directly. Therefore, touch feeling of touch panels is important. However, methods for evaluating touch feeling of touch panel surfaces have not been established. In this study, an objective evaluation method for touch feeling of touch panel surface is established based on the tactile sensor system developed in previous studies. Firstly, the sensory evaluations for touch panel samples with different surface treatments were conducted. Next, touch panel surfaces were measured by using tactile sensor system, and evaluation parameters by using sensor output were calculated in order to evaluate touch feeling. Finally, the evaluation parameters were compared with the results of sensory evaluation. As a result, it was confirmed that the tactile sensory system is useful to evaluate the touch feeling of touch panel surface objectively.

    This paper describes development of a roll type contact stimulus evaluation system. In this study, contact force applied on skin with diaper and diaper friction are measured as the contact stimulus. First, in order to measure the contact stimulus, contact stimulus sensor is fabricated. The sensor comprises a polyvinylidene difluoride (PVDF) film and strain gauge. Next, roll type contact stimulus evaluation system is designed. In the system, roundish body part of infants such as hip is simplified into cylindrical shape. The relative motion of the hip joint is simplified into rotational motion of the cylinder. Based on the features of sensor outputs, some parameters are proposed in order to evaluate the contact stimulus. Then, three kinds of commercial disposable diaper are used as measuring objects. Sensory test about contact stimulus of the diapers are carried out on adults. And using the developed roll-type system, measurement of the diapers are conducted. By comparing the sensory evaluation value with the evaluation parameters calculated from sensor output, it is found that some evaluation parameters for the diaper obtaining the strongest "prickly sensation" and "irritated sensation" are bigger than others. From the results, it is confirmed that the developed system is useful for estimation of contact stimulus.

    This report proposes a hardness detection sensor that aims to evaluate the hardness of biomedical tissue. The sensor is composed of a hard cylinder material, a soft column material, and two thin plates and strain gauges. The forces which act on the soft and hard materials are measured by strain gauges through a deformation of the thin plates. The ratio of the forces evaluates Young's modulus of a soft contact object.

    In this paper, a haptic sensor system for evaluation of human hair under dry and wet conditions is developed. The polyvinydene fluoride (PVDF) film, which is a kind of piezoelectric materials, is used as the sensory receptor. The sensor consists of acrylic base, a silicone rubber, a PVDF film, and projections for the contact to objects. The sensor output is obtained by contacting and scanning of the sensor on the objects. Panels imitating the physical and chemical properties of human hair are fabricated and used as measuring objects for stable measurement. The surface of the sensor projection and sensor structure are improved in order to measure under wet condition as well as under dry condition. Panels cleaned by hair care products are evaluated by the improved sensor, and the sensor outputs are compared with human sensory evaluation. It is confirmed that the sensor outputs have a clean correlation with human evaluation.

    Human skin, which mainly consists of epidermis, dermis and hypodermis, is the largest organ of a human body. It has a lot of roles, for example, protection function, moisture maintenance function, and sensory function. Moreover, it becomes a parameter that shows the health condition and beauty, because the skin is the outermost layer of a human body. Therefore, the development of the sensor that can measure the skin conditions in various parts of the body is demanded. However, sensors that had been developed before can measure limited parts of body or can measure only in limited condition. In this paper, the sensor that can measure various parts of human body in various conditions is developed and evaluated by measurement of the artifical skins that have various hardness and roughness.

    This paper focuses on a development of a 3D drag sensor for detecting the catheter's contact conditions. The sensor is composed of a cylindrical nonmetal material and three strain gauges. The load that joins the point of the sensor is measured with the strain gauges. The gauges are put on the side of the nonmetal material at intervals of 2π/3 radians. The output voltage of the gauges are approximated by sinusoidal functions with a phase difference of 2π/3 radians. The equations relating the sensor output with the contact conditions are formulated in the three gauges output. We show that the contact angle with object and the load that joins point of catheter are estimated by the gauges output voltage and approximated sinusoidal functions.

The wearable sensor system is fabricated by combining the sensor with these parts in order to teach the user the recognition results by real-time voice output. For the improvement of the performance, the classification is carried out using plural classifiers, each of which is based on multi-layer perceptions. The multi-layer perceptions are used in the form of dichotomizers, each solving a two-class classification problem. The sensor system is examined experimentally whether it is effective to recognize Braille. The obtained results show that the wearable sensor system is effective to recognize Braille.

    Touch is the most frequency used action to gather the outside information. In our daily life, various kinds of things are touched with fingers and their features are extracted and evaluated unconsciously. Tactile sensation gives not only perception of contact but also various kinds of feelings, like "rough", "soft", "warm", "comfortable", and so on. Thus, the sense of touch is indispensable to our life as well as the sense of sight. In the tactile function, contact, stroke, and other actions are used to an object for the tactile perception. It seems that most of the tactile sensors developed so far have been functional to the measurement of just force magnitude, while a few sensors are available for the rating of the feelings on an object material. This paper introduces an active palpation sensor for detecting the prostatic cancer and hypertrophy and a sensor for monitoring human hair conditions.

    This article reports a study on the development of a new ER hydraulic draft gear as a relief buffer for the purpose of lower the coupler force acting between the failed and the relief bullet train set. A prototype buffer consists of a hydraulic cylinder, an ER bypass slit valve, and a PID feedback controller was developed. The damping force is developed in the ER fluid both through the bypass slit and at the piston-cylinder gap. First, theoretical analysis of the fluid characteristics of the buffer is conducted. Next, the primary functions and performance of the buffer as an active buffer are investigated experimentally. Theoretical analysis and experimental results show that the coupler force of the railway vehicle can be controlled effectively by using the proposed electrorheological bypass damper.

    This paper reports a study on the development of a new type of artificial rectum valve system using the SMA actuator. At body temperature, the valve presses on the rectum to clog the evacuation. When the SMA actuator is actuated by providing electric energy to it, the valve opens to enable evacuation. To verify the function of the artificial rectum valve as an anal sphincter, preliminary experiments and in vivo animal experiments were conducted. The experiments verify that this valve works well as an artificial rectum valve.

    This paper is a study on the development of a sensor for measuring tactile sensation. Human warm feeling on fabrics is compared with the sensor output. At first, warm feeling on each sample is collected through the questionnaire based on the paired comparison semantic differential method. Furthermore, human's motion for the evaluation of the warm feeling is investigated. Next, a sensor using the pyroelectric effect of a PVDF (Polyvinylidene Fluoride) film is fabricated. The surface of the sensor is heated through the temperature control. Then the sensor is moved and contacted with an object through the trajectory control of the contact pressure in order to collect output voltage of the pyroelectric effect. Finally, the measurement using the sensor is carried out on the samples. Comparison with the results shows that the PVDF sensor is available to evaluate the warm feeling.

    This paper is a study on the development of a wearable sensor system for reading Braille. The study is intended to develop a compact tactile sensor system which uses a PVDF (Polyvinylidene Fluoride) film for the sensory material. The sensor is mounted onto a fingertip as the wearable system and is moved over Braille manually to obtain the output. Since the unsteady movements yield variations in the waveforms, a robust recognition system is introduced. The developed recognition system consists of three components as follows. First, the signal inputted to the system is divided into individual signal regardless of the variation in the waveforms. Next, those signals are transformed into effective feature vectors in order to suppress the variation. Finally, those vectors are classified and the recognition results are obtained. The classifier is composed of organized dichotomizes made from multi-layer perceptrons to enhance the classification accuracy. To carry out experimental verification, test signals are inputted to the recognition system and the performance of the system is evaluated. The obtained results show that the robust recognition is achieved appropriately.

    This paper reports a study on the development of an artificial rectum valve. An artificial rectum valve is developed using an SMA plate as the actuator. At body temperature, the SMA plate takes an arc shape, and the valve closes the rectum by the force of a bias spring. When the SMA plate is heated by the electric current that flows through the nichrome wire to the plate, it recovers its original flat shape, and then opens the valve to enable the evacuations. The motion characteristic is studied from preliminary experiments, which confirms that the valve closes at the body temperature and opens when the SMA plate is heated. Furthermore, to verify the function of the artificial rectum valve as an anal sphincter, in vivo animal experiments were conducted using dogs. The experiments verify that this rectum valve works well as an artificial and sphincter.

    This paper is a study on the development of a haptic sensor system for monitoring skin conditions. The sensor is an assembly of layered media. The base of the sensor is a stainless plate, on which a sponge rubber, a PVDF film with electrode patches, a protective surface layer of acetate film and a gauge are stacked in sequence. The sensor is attached to the forefinger and pressed against the surface of the skin. It is then slid over the skin to collect surface morphological features. Through the fundamental experiment using the artificial objects, two evaluation parameters characterizing skin conditions are determined. One is the variance of the signal processed with a wavelet analysis, which is the index of roughness. The other is a parameter showing the dispersion of power spectrum density in the frequency domain, which is the index of softness. The sensor system is then applied to the clinical test of skin with various conditions. Results show that the sensor output well describes the skin conditions and represents the subjective evaluations of dermatologist.

    This paper is a study on development of a sensor system for measurement and valuation of human touch feeling. First, a soft tactile sensor made of a PVDF (Polyvinylidene Fluoride) file patch and rubber layers is assembled and slid over the same sample fabrics to collect the surface tactile information. The features on the collected data are then extracted by calculating the variance of output signal and the intensity of power spectrum density on medium frequency range. And the features are compared to the specific feelings on wearing are collected on twenty-six clothes through the paired comparison method handed onto 5 subjects. Further, the features extracted from sensor output are compared to results of the factor analysis for touch sensation. These results show that the PVDF sensor well describes the tactile perception of human touch feeling.

    This paper is concerned with the development of an active palpation sensor for detecting the prostatic cancer and hypertrophy. The receptor of the sensor is a polyvinylidene fluoride (PVDF) film placed on the surface of a sponge rubber layer. It is fixed at the end of a slender bar and, being protected by a medical rubber glove, inserted into the examinee's rectum. After positioned face to face to the prostate gland, the sensor probe is driven sinusoidally at about 50 Hz with peak-to-peak amplitude 2 mm. The voltage signal from the PVDF film is integrated over the sampling period and used as the output of sensor for extracting the features of the collected data. The evaluation of stiffness by the sensor on 27 normal and unhealthy prostate glands are compared with the results of diagnosis by the doctor's palpation. It is shown that the output of sensor becomes greater with an increase of the stiffness of the prostate gland, which has good correlation with the doctor's evaluation on the stiffness. Further results on the laboratory test reconfirm that the present sensor well discriminates the stiffness of the prostate glands in vivo and non-invasively.

The base of the sensor is an aluminum shell, around which a rubber sponge layer, PVDF film, a protective layer of acetate film and gauze are applied in sequence. The sensor is attached to the tip of an elastic cantilevered beam and pressed against an area of skin. It is then moved by hand over the skin to allow the sensor to assess surface morphological features. Characteristics of the data are extracted by calculating the variance and distribution of power intensity over several segmented frequency ranges. The test was examined to estimate the age of skin condition by multiple regression analysis. From the obtained results, it is enabled that this sensor system divide that prime layer and young generations roughly.

A non-contact, compact induction heating system using the power transmission coils is introduced, which is consisting of the oscillation, regular voltage, amplifier and transmission circuit. It transmits the electric power to the artificial valve inside the body transcutaneously. The transformer is designed so that it is driven by the battery considering that it be used outside the buildings. From the experimental results, it is shown that the proposed transformer system driven by the battery supplies enough power to the urethral valve to open the choked urethra.

    A study on monitoring the slicing condition on cutting a silicon crystal ingot by ID(inner-diameter) saw blade is presented. The acoustical and vibration signals during cutting the ingot are measured by a piezoelectric 3-axis load sensor which is fixed onto the mount of the silicon ingot. The collected data is first transformed by FFT analysis and then the logarithm of the power spectrum is decomposed by wavelet transform in order to categorize the state of the wafer surface damage by the signals. Several examples have been discussed and the results show that the proposed signal analysis method is useful for the evaluation of the wafer quality and the slicing condition of ID saw blade.

    This study planned to develop a labor simulator for learning tool on basic research. The differences of the motion during the conduct of labor between students and experts were examined. The pressure sensor using pressure sensitive conductive ink was used to measure the pressure of the finger and the palm during the conduct labor. We measured the pressure during the conduct of labor on 13 students and 17 experts. Then the characteristic of the motion experts were extracted by the results from pressure sensor and motion picture. Expert mean pressure are higher than student ones and in addition the large variation of expert were showed during the conduct labor. The correlation coefficients between the pressure profiles of right hand and left hands during the delivery of the external occipital protuberance were calculated. It is founds that the best conduct labor method is frontage position method because It is the highest rate of synchronizing between right hand and lift hand during the conduct of labor.

    触覚・触感に基づくQOLテクノロジーの創出として、触診代替え用の触覚センサの開発ならびに点字読み取り用センサの開発について取り組んだ。触診代替え用センサではヒトの触診との併用を可能とする爪装着型の硬さ計測用センサを開発した。センサ素子にはPVDFフィルムを用い、シリコーンによって作成された生体模擬組織を対象として特性計測を行い対象物が硬くなるにつれセンサ出力が小さくなる傾向を確認した。またセンサと対象物を2次元のばね質量系としてモデル化を行い、強制振動のシミュレーションを行い、センサ出力の傾向についての妥当性も確認した。また固体高分子SPE素子を用いて曲率計測用センサを作製し特性計測を行い、異なる曲率のサンプルを対象に、センサの方向性やサイズの影響について調査した。また、ヒトの触覚について圧電素子を用いた触覚ディスプレイを作製し、粗さや硬さに対する振幅や周波数の影響について調査した。得られた結果より、硬さにおいては接触面積の変化が大きく依存するであろうこと、粗さについては、振幅が大きいほど粗く感じることやパチニ小体やマイスナー小体の敏感な周波数帯域で粗く感じることが分かり、触覚センサを作製するうえで有効な設計指針が得られた。 また点字読み取り用センサでは、これまでのセンサを基にユーザービリティの向上を目指し、点字に対するセンサの直進の向上のための車輪装着型センサの作製、点字とセンサを的確にセット出来るようにセンサガイド部の改良、またセンサとが点字に対して回転しないようにゼンサグリップ部の作製を行った。これらによって性能の向上が確認できた。

    本研究では歩行のトレーニングの度合いやその成果について筋音図を用いて提示する装置を構築することを目的としている。トレーニングの前後での筋音図を測定し、トレーニングの評価や筋の状態について検討を行う。また、筋力計を用いて筋力も併せて測定し筋力の増減とも関連して筋音図との関係を調査する。今年度は、歩行のトレーニング用の下腿の中でも腓腹筋を対象として調査を行った。昨年度までに作製した高分子圧電材料(PVDFフィルム)を用いた筋音センサならびに計測用システムを用い計測を行った。また筋肉の成分についても同時に調査を行い関係について検討を行っている。筋音の計測ではセンサ出力の平均周波数と分散を求める信号処理を行い、個人差、筋肉疲労などの関係をより詳細を調査することが重要であることが分かった。負荷の掛け方や計測の容易さから、対象を腓腹筋とすることとして、さらに検討を進めている。下肢においては負荷となる発揮底屈力を一定荷重にすることが困難であり、モニターによりリアルタイムで発揮底屈力を表示させるシステムを構築し、本人はそれを目視で確認し下腿の力を調整し一定とすることが可能なシステムを準備した。500秒間の最大随意筋力の5%と10%の発揮底屈力を負荷とした場合の平均周波数と分散について調査をした。5%負荷時には平均周波数は増加し減少すること、10%負荷時では減少のみであることを確認した。また分散では両条件でも増加することが確認された。そこで5%負荷時の計測についてエアロバイクを用いた運動負荷前後での計測を行い比較した。この結果について平均周波数、分散ともに運動負荷前後では全く異なることが得られた。

    In this project, an active-controlled damper for railway vehicle couplers was developed in order to improve the ride comfort of the passenger railway trains. The research results were summarized as : a) Acceleration of railway passenger trains during the starting-up and the stopping was collected. A real time filter for calculation the jerk from the acceleration was constructed. Relationship between ride comfort and acceleration/jerk was investigated. The results show that the root-mean-square of both acceleration and jerk affect the ride comfort of passengers. b) Based on the theoretical analysis of the fluid dynamics of the Electrorheological (ER) fluid, a prototype of an active controlled ER damper consisting of a hydraulic cylinder and a bypass slit valve was developed. The fundamental force-velocity characteristics of the prototype were investigated using the prototype through experiments, and function of the prototype was verified. Also a real size damper was designed. c) Active control experiments were conducted using the prototype. Experimental results confirmed that at constant velocities, the damper capacity could be increased by 100%, and piston reactive force can be retained at the prescribed target with satisfactory accuracy. Experimental results also confirmed that under the condition of sinusoidal displacement of the piston, which simulates the real running condition of a passenger train, the piston reactive force can also be retained at the prescribed target. Further, experiments also verified that the piston reactive force could be controlled to follow the preset trace, which suggested that the developed damper can be used to control the jerk. d) It is also understood that because of the non-uniformity of the ER fluid, in order to obtain higher control accuracy in a wide range, further studies of a more sophisticated control method should be continued.

    本研究は触診用アクティブセンサシステムを開発するものである。特に男性高齢者の病気として現在著しく増加している前立腺癌・肥大症用の触診について着目し,これらの判別可能とする触診センサの開発について昨年度に駆動機構部とセンサ部について臨床実験を通して操作性を考慮した指装着型のセンサの設計および試作を行った。得られた結果を要約すると以下のとおりである。 1 昨年まで得られた知見と同様にセンサ部については高分子圧電材料と適度な硬さの母材のゴムから構成されるセンサが有効であるが、昨年度から引き続き検討してきた駆動部構造について操作性の向上を目標とした。検討した駆動部については、指先のセンサ部と分けることを提案し、センサ装着した指先への振動により駆動を実現した。具体的には小型の振動子を指根元部に装着し駆動させ、そのとき対象物へセンサを介して指を当てセンサ出力を得ることによって対象物の硬さの判別が可能であることを確認した。特に、硬さの既知な対象物においては、センサ出力と硬さが比例関係であることが分かった。 2 体内深部の測定を可能とするように、指先へ装着するセンサ部をさらに小型化した。具体的な方法としては、センサと指の固定具が大きくなってしまうことに着目し、指サックにセンサをあらかじめ固定して、指サックに指を挿入するだけで自動的にセンサと指の安定な固定を実現した。これよりセンサ部の小型化を実現した。 3 1と2で提案した、駆動部とセンサ部を用いて臨床実験を行い病変部の症状とセンサ出力の比較をした。センサ出力より、硬さ測定は有効に行われ病気の症状の度合いが測れることが確認された。

    本研究は視覚障害者特に後天性視覚障害者の点字学習支援となる点字読み取りセンサシステムの開発を行うものである。 連続文字読み取り可能なセンサシステムの開発を行うために,高分子圧電材料(PVDF)フィルムを受感材としたセンサを用いサーボモータで駆動されるスライダ機構に搭載し,様々な走査速度で点字上を掃引した。前年度の結果より、走査速度を変化させても、センサ出力の変化は反応時間および出力変化に差が現れるものの、時間と振幅について無次元化することによって、単文字波形と大きく異ならない特徴が抽出でき、単文字への切り出し用条件を用いる事により連続文字から単文字へ切り出す事が可能である事が確認された。本年度はこの結果を基に認識アルゴリズムについて検討および性能実験を行った。単文字として切り出された信号への処理として,各文字波形をベクトル形式へ変換することを考えた。切り出された各文字波形は,データ長が均一でなかったりするためそのままでは扱いにくく,切り出された各文字波形を低次の適切なベクトルへ変換することが必要である。またベクトルへの変換としては,波形の伸縮や起伏の特徴の変化等が生じることを考慮し,このような影響を抑制可能な方法が望まれた。そこで本研究では切り出された文字波形の内で変換に必要な部分を指定し、その部分内でm個の区間に等分割し区間ごとに電圧値を平均化したものをベクトルの成分とし、さらにその部分でのベクトルの成分の絶対値の総和で除す正規化m分割処理を行いベクトルとした。さらにこの上述の入力用のベクトルを同手法で用意したテンプレートベクトルと比較する事により識別結果を得るテンプレートマッチング法を識別器とした。これらの認識アルゴリズムを用いて行った性能実験より走査速度によらず90%の正解率が得られる事が確認された。

    摘出したイヌ大腸の内外径、壁の厚さを測定した。その値から、イヌ大腸の内腔開閉に適した形状記憶合金バルブを作製した。バルブは常温では閉鎖しているが、熱が加わると開放する仕組みとした。閉鎖した際の内腔が狭すぎると大腸の壊死などが起こると考えられるが、広すぎると逆に内容物の漏れが起こること、開放した際には十分な内腔を確保すること、に留意し作製した。作製したバルブを用い、麻酔下のイヌで実験を行った。バルブをイヌの直腸に取り付け、まず、無理なく取り付けられること、閉鎖した状態で大腸に悪影響がないことを確認した。バルブの口側大腸内腔で内圧測定を行いながら、さらに口側の大腸から潅流用のカテーテルを内腔に留置、固定した。また、バルブの肛門側大腸に小切開をおき、バルブを通り抜けた内容物を観察出来るようにした。内圧を測定しながら潅流用カテーテルから生食を滴下させ、バルブから肛門側へ内容物が漏れてしまう内圧を測定した(バルブの耐圧試験)。その時点で潅流を中止し、内圧が一定となって内容物が漏れなくなった時点まで待ち、バルブに熱を加えバルブ温度と内圧の関係を測定し、かつ内容物がバルブより肛門側に漏れ始めた時期を記載した。その結果、バルブの耐圧は、300mmHgであり、その後潅流を中止したところ、200mmHgまで内圧が低下して一定となった。ここでバルブの温度を上昇させると、42度となったところで急激に内圧が低下して内容物がバルブの肛門側へと流れ始めることがあきらかとなった。これらの結果から、今回作製したバルブは実験上は十分な性能を有していると考えられた。

    This study deals with the development of artificial valves used as sphincters for the luminal organs such as the urethras or the rectums. Aiming at the realization of durable, practical and easy-operating implanted artificial valves, materials, mechanical structure, motion characteristics, motion control, bio-compatibility and simplicity of clinical implantation of the valves are studied in this project. First, using a thin plate of the NiTi shape memory alloy (SMA) as the actuator, an artificial urethral valve for the treatment of incontinence of urine was developed. Transcutaneous energy transmission system providing energy to the implanted valve was also developed. Further effort was made in the improvements of the mechanical structure of the valve and the efficiency of the energy transmission. A closed loop thermal control system was developed and integrated into the energy transmission system in order to prevent over-heating of the SMA surface. Through animal experiments using dogs, the efficiency of the whole system as an artificial urethral sphincter was verified. Based on the experience and achieved results so far, in the last fiscal year of the project, effort was made in expending the application of the valve to the treatment of incontinence of feces. A rectal valve was developed. Structure of the valve was redesigned to meet the need of the rectal valve. Higher efficiency of transcutaneous energy transmission was obtained through further improvement of the transmission system. More reliable information transmission circuit was developed to obtain a more stable thermal control of the SMA actuator of the valve. Finally, the rectal valve, transcutaneous energy transmission system, and the thermal control system were tested by animal experiments using dogs. Experiment results verified the usefulness of the developed valve system as an artificial rectal sphincter. In conclusion, an artificial urethral valve system and an artificial rectal valve system using SMA as actuators are developed. Efficacy of their function as artificial valves used as sphincters for the luminal organs is testified.

    前立腺癌および肥大症の診断は,前立腺癌は凹凸不整の増殖で高度が著しく増加しているもので肥大症は軟らかな左右対称の肥大という特徴に基づいた医者の示指を肛門より挿入して行う直腸内触診法に超音波探触子を用いた超音波断層法を併用して行うのが一般的である.しかしながら触診は曖昧な人間の指感覚に依存するため,診断の結果は医師の経験に大きく影響される.このため,より客観的に診断結果が得られる測定方法の開発が求められている.高分子圧電ポリフッ化ビニリディン(PVDF)フィルムは,圧力パルスに対する応答が人間の皮膚の感覚受容器の一つであるパッシーニ小体の応答によく似ていることが知られており、触覚センサの受感材として注目されている。 以上の事より本研究では前立腺を触診しその硬さを測定・評価するアクティブセンサを構築するものである。本年度は具体的にPVDFフィルムを受感材として用い、センサ部を手に装着し前立腺と安定した接触を可能とし駆動機構を有するアクティブセンサの開発を行った。駆動部は指の部分にはなく、振動伝達部のみを指先端部分に導入することより小型化を可能とした。またセンサと対象物の間に凹型のセラミックスを導入することにより、前立腺のような球形でも安定した接触が可能となり、安定したセンサ出力得ることが可能となった。臨床実験では、陰茎、前立腺の測定に応用しその有効性について確認したところ、癌・肥大症の違い、さらに癌の病状の違いが分かるセンサ出力を得ることが可能となった。

    尿失禁とは不随意に起こる尿漏れで,社会的衛生的に問題となるものであり,その治療法の確立が強く望まれている.しかしながら尿失禁の原因は多種多様で,患者の年齢も小児から高齢者にわたることから,その治療は画一的とならず大変困難なものとされている.約10年前に画期的な尿失禁治療法としてシリコン製人工括約筋が開発されたが,構造が複雑で高価でありさらに長期使用後には駆動液が漏れる等の問題を生じている.形状記憶合金(SMA)の中でもTi-Ni合金は優れた記憶能力を持ち,熱を加えるだけで簡単に大きな変位や大きな力を発生させることができるため,その基本的特性や応用に関して多くの優れた研究がなされている.形状記憶合金を医療分野に応用する試みは1970年代の後半から米国を中心に進められており,これまでにも医療用クリップ,歯列矯正および骨折治療用内副子,人工心臓用人工筋などへの応用が試みられ,一部はすでに医療用治具として実用化されている。 本研究は尿失禁治療法のひとつとして,形状記憶合金をアクチュエータとする尿道開閉用人工バルブの開発を行うものである.本年度は二方向性形状記憶合金の薄板からなる人工尿道バルブの改良および非接触経皮的電力伝送システムを用いた電力実験を行いバルブ及びエネルギ伝送システムについて検討を行った.得られた結果を要約すると以下のようになる。 (1)試作改良を繰り返し小型化さらに体内に埋め込んでも安全な形状のバルブを製作し、動物実験によってその動作特性を確認した。 (2)電力伝送システムは発振・増幅・伝送回路から構成された小型の経皮的電力伝送装置を開発し、実験室レベルおよび動物実験により動作確認を行った。実際,供給電力は約7Wで開発したバルブの駆動が出来,携帯としての電池駆動の可能性が示せた。

    The purpose of this project is to development a practical and quantitative structural health monitoring technique for intelligent structure system. Since the piezoelectric actuator can be driven at very high frequency and the piezoelectric sensor is very sensitive to the rate of strain changes, the piezoceramic patches structures were introduced as actuators and sensors to generate and receive a high frequency wave propagating in the structure. Since the electromechanical coupling between the piezoelectric material and the structure the physical changes in the structure can be captured efficiently by monitoring the PZT electric impedance this technique is very sensitive to detect the presence of incipient-type damage such as small cracks or loose connections. Furthermore an advanced technique for assessment of the location and characterization of damages by measuring longitudinal wave propagation was developed. In order to reduce the numbers of the PZT patches in the structure for cuffing down the cost of wiring, the technique how to reducing piezoelectric patches in the structure was also investigated. The obtained results have been presented at the SPIE's 6th Annual International Symposium on Smart Structures and Materials. Further, a real time cutting condition monitoring system on slicing 300mm silicon ingot was also developed because the silicon ingot should be cut to yield wafers surface as flat and smooth as possible. The circumferential, radial and normal cutting forces were measured by using the piezoelectric 3-axis load sensor fixed onto the mount of the silicon ingot. The results show that the cuffing condition of the saw blade is clearly predicted by analyzing the high-frequency signal with FFT and wavelet transforms, and the on-line monitoring system is validated experimentally useful for evaluation of 300mm silicon ingot slicing machine.

    現在一般の人が皮膚の微妙な変化を知る方法としては鏡を見る,自分の手触り感に頼るなどの主観的な方法しかない。客観的な肌状態の評価方法としては肌荒れや皺を画像的に取り込むマイクロスコープ,表皮水分含有量を計測する経表皮性水分喪失分量器や高周波伝導度計,皮膚組織内の赤血球の動きを計測するレーザードップラー血流計測器,さらに皮膚の伸展性や粘弾性を計測する皮膚吸引カトメーターやねじりメーターがすでに開発されており医療現場に応用されている。しかしながら,これらの機器は高価でありその取り扱いに専門的な知識を必要とする。そこで本研究は受感材として高分子圧電フィルムを用いた触覚センサを試作し、保護膜などを使用し改良を行った。試作改良したセンサを用いてまず、掌、腕、足の裏など表面粗さの明らかに異なる部位について測定し信号処理を行い判別可能であることを確認した。更に精度を向上させために、同じ部位の皮膚を薬品で意図的に荒れた状態にし、薬品を使う前と後で計測を行いデータを解析した。その際に比較検討のために、皮膚表面の電気伝導度を測定するSkiconメータと水分損失量を測定するエバポリメータにより、脱脂前と脱脂後の値を測定した。それらとの対応のために、現在肌の状態を表すのに最適な情報をどのように表すべきか様々な信号処理を行っている。またこれらの実験によってセンサ表面にの保護膜状に付ける砥粒を対象とする表面粗さに対応できるようなものにする必要があり、さらにPVDFをはりつけた母材については対象物との接触で生じる振動を吸収していない物にする必要があることが分かった。
