    Magnetic resonance imaging (MRI) is the key technology to investigate anatomy and phyisiology by a non-destructive imaging method. The analysis of molecular structures in nano-scale plays an important role for future nanotechnology. Since the spatial resolution of conventional MRI sytsems is limited to tens of micrometers, the high sensitive magnetic sensor is required for imaging in nanometer spatial resolution. The luminescence of nitrogen vacancy (NV) centers in diamond is sensitive to magnetic field, which applicable to MRI at room temperature through optical detection. Si scanning probes with a diamond particle having the NV centers are developed. Firstly, the diamond particles with the NV centers is deposited on a dummy wafer by microwave plasma chemical vapor deposition (MPCVD) with additional N_2 gas. While a graphite component in the diamond particle is observed by Raman spectroscopy, and the luminescence of the NV centers has been slightly detected. After XeF_2 etching and annealing, diamond particles which own NV centers are picked up and fixed onto the fabricated probe pillar using a glass needle and glue.

    The Q factor enhancement of Si resonators using nonlinear damping is investigated for highly sensitive resonant sensors. The thermomechanical noise, which limits the physical resolution of resonant sensors, can be improved by increasing the Q factor. In this paper, the nonlinear damping effect of thin Si resonators was investigated and the Q factor enhancement caused by nonlinear damping is measured. The resonator thickness used for the Q factor measurements are 100, 400, 800, 1500 nm. The Q factor of the 100 nm-thick resonator is dramatically increased as its vibration amplitude become larger, while the Q factor change become smaller as the resonator thickness become thicker. These results show that Si resonators have the nonlinear damping effect, and the large Q factor enhancement by this effect is markedly observed in the thin resonator. It is concluded that the Q factors of nanomechanical resonators can be increased by only adjusting its vibration amplitudes.

    This work aims at developing a miniature Fourier transform infrared spectrometer (FTIR) for monitoring body components using an attenuated total reflection (ATR) method. An electrostatically driven Wishbone Si micro-interferometer with a size of 8×8 mm^2 and elliptic ATR crystal are developed using a microfabrication technique. Micro-corner cube mirrors is fabricated and assembled on the interferometer. The corner cube mirrors on the interferometer can be rotated by approximately 3 degrees. The elliptic ATR crystal is fabricated from a float-zone Si wafer using laser dicing. The measured transmittance of the elliptic ATR crystal is 44% larger than that of a rectangular ATR crystal.

    We have developed a resonant thermal sensor system for biological samples. The measurement principle relies on the resonant frequency shift of the resonant thermal sensor due to the temperature change. Brown fat cells, which are frequently used for metabolism researches, attract our interests to solve obesity, metabolic syndrome, and so on. To measure its thermal characteristics in single cell level, a heat loss to surrounding environments and a vibration damping should be solved when resonant thermal sensors are immersed in water. To solve these problems and realize highly sensitive thermal measurements, a resonant thermal sensor was partly placed in vacuum, and another end was in microchannel as a sample stage in a microfluidic chip. They were connected physically and thermally by a heat guide. The heat from the cell is conducted to the sensor via the heat guide, and measured. A fabricated device was evaluated by using laser Doppler vibrometer. The thermal resolution of the device was 5.2 pJ. The single brown fat cell was set on the sample stage, and generated heats were measured with and without stimulation. With the stimulation, pulsed heats were observed, which have not observed in bulk measurements. With the stimulation, gradual and long heat generations were caused similarly with bulk measurements. We have succeeded in detecting the heat from single brown fat cell by using the fabricated device.

    © 2018 IEEE. We propose an FBAR oscillator for the wireless system used in the superhigh-frequency (SHF) band or extremely high-frequency (EHF) band. At these frequencies, a high-precision standard clock is required, and it is preferable that the clock frequency be set to a GHz-order band to mitigate the amount of frequency multiplication. In this study, we developed a 3.5 GHz band thin-film bulk acoustic resonator (FBAR)oscillator and stabilized it to the hyperfine transition of alkali atoms 87 Rb. Consequently, a short-term frequency instability of 8.5 × 10- 12 at 1s was achieved.

    © 2016 IEEE. Nitrogen vacancy (NV-) centers possess exceptional sensitivity to magnetic field even under ambient condition. The optically detectable electron spins and the atomic size make it a promising candidate for advanced magnetic resonance imaging (MRI) technique with nanoscale spatial resolution. In this work, diamond particles with NV-centers were deposited by microwave plasma chemical vapor deposition (MPCVD) under gaseous N2dopant and were fixed on the fabricated scanning probe as a magnetic sensor. While the existence of NV-center was determined by Raman spectroscopy, the photoluminescence intensity at 2.87 GHz microwave frequency was decreased by an optically detected magnetic resonance (ODMR) system. It implies that the NV-spin state can be manipulated and read out using optical excitation.

    © 2016 IEEE. This paper presents an assembled comb-drive XYZ-microstage with large displacements for the scanning of magnetic resonance force microscopy (MRFM) at cryogenic environment. The scanning XYZ-microstage with little affection to the thermal variation and magnetic fields is required. The comb-drive XYZ-microstage is assembled with an XY-microstage, two Z-actuators and a silicon base substrate using a microassembly technology. For measurements, a sample of 1, 1-Diphenyl-2-picrylhydrazyl radical (DPPH) is glued onto the assembled XYZ-microstage. The imaging system is consisted of the scanning XYZ-microstage with DPPH sample, a sensitive cantilever sensor with a small magnetic particle, a fiber-optic interferometer to detect the vibration of the cantilever and a radio frequency (RF) coil. The measurements are performed at low pressure in a vacuum chamber. The vibration of the cantilever sensor based on magnetic force from electron spin resonance (ESR) spectroscopy can be detected through adjusting the magnetic field intensity of the RF coil.

    © 2016 IEEE. In this work, we present the electrodeposition of nickel (Ni)-carbon nanotube (CNT) composite thin films and evaluate the CNT weight percentage in films using energy-dispersive x-ray spectroscopy (EDX). To increase the CNTs codeposition, the CNTs are functionalized with positive charges and the composite thin films are deposited with different current waveforms. Furthermore, two kinds of composite films with CNTs annealed at different temperatures (1200°C and 2600°C) were compared for their CNT contents also the nanoindentation hardness of the composite films were evaluated. The composite films with a maximum CNT content of 5.4±2.0 wt% with a hardness of 17.0±3.0 GPa are achieved in the case of CNTs annealed at 1200°C. In the case of CNTs annealed at 2600°C, the CNT content of the composite was found to be 3.7±2.0 wt% with hardness of 14.9±3.0 GPa. For all Ni-CNTs composites, mechanical strengthening was found in the composites compared with pure Ni films.

    © 15CBMS-0001. We have developed a highly sensitive thermal detection device based on a Si double-supported resonator to measure a heat from single cells. The double-supported resonators are expected to have a large temperature coefficient of the resonant frequency (TCF). The sensor is vacuum-enclosed in a microfluidic chip, which make it possible to measure the heat from cells captured in liquid with negligible heat loss to the surrounding and damping. The TCF of the fabricated sensor is -590 ppm/K, and 0.16 nW/√Hz of the thermal resolution is achieved. Then, the thermal measurement of a single brown fat cell is succeeded by using the fabricated device.

    ダイヤモンドMEMS高温磁気センサーを開発するために、高い品質因子(Q値)を持つダイヤモンドMEMS共振子及びダイヤモンドの上に高温磁歪材料の成長は重要です。2018年以来、ダイヤモンドMEMSの高速成長技術を開発したによって、Q値20000を超えた高品質ダイヤモンドMEMSの作製に成功してきました。続いて、(1) R3年度は、ダイヤモンド高速ドライエッチング技術を開発に成功し、エッチング速度を20倍に改善し、Q値を20000から200000に向上しました。(2) 一方、ダイヤモンドの上に成長された磁歪材料FeGa薄膜の結晶構造、表面形態、磁気特性に及ぼす成長条件の影響を調査しました。 表面粗さが1nm未満、保磁力(Hc)が26.2 Oe、飽和磁化磁場(Hs)が450 Oe、残留磁気比(Mr / Ms)が0.9を持つ優れた結晶化磁歪材料FeGa薄膜得られました。(3) ダイヤモンドMEMSのQ値に対するFeGa薄膜の影響も調べしました。Q値が8000から3000に低下しでも、磁気センシングにはまだ十分な高さであることがわかりました。(4) 更に、室温から高温700°CまでダイヤモンドMEMSの共振周波数法によって、ダイヤモンドヤング率の温度依存性を研究して、ダイヤモンドMEMSの高い熱安定性(6ppm/K)をわかりました。したがって、ダイヤモンドMEMSは優れた熱安定性を持ち、高温磁気センシングへ応用を期待しています。

    Magnetic resonance force microscopy (MRFM) can obtain three-dimensional distribution images of internal spin density of a sample with a non-contact and non-destructive method. In this study, we developed an MRFM, which can make an imaging of magnetic resonance phenomena inside a small sample at atmospheric temperature and pressure. By using a highly sensitive Si nanowire-type magnetic force sensor with a magnetic sphere at its apex and precisely defining the response function required for image processing, we have made it possible to image a wide range of electron spin density distributions with high precision even with a small number of observed data. Furthermore, by using a Fourier transform that uses a simple convolution in wavenumber space with a noise parameter for the response function, the time required for 3D imaging processing has been successfully reduced, enabling highly accurate imaging even under normal temperature and pressure.

    In extreme environments, such as high temperature or strong radiation in nuclear power plants, automobiles, and propulsion systems for combustion control in aerospace, etc., thermally stable and radiation hard electrical logic circuits is in demand to safely respond and control the electrical signals quickly. Conventional semiconductor devices suffer from thermal leakage current, reduced power handling, and low on / off ratio at high temperatures. Nanomachine switches, in which the on-off operation is controlled by electrostatic actuation with a physical air / vacuum gap, have nearly zero leakage current even at high temperatures and an infinite on / off ratio. In this research, we aim to develop diamond nanomachine logic circuits that can be operated in extreme environments in order to overcome the problems of the conventional switches by utilizing single crystal diamond MEMS technology.

    The micro fluidic chamber with narrow gap for high pressurized fluid has been designed and fabricated. The carbon dioxide (CO2) is injected into the narrow gap spaces of 0.5 μm and 1.6 μm. Their thermal resistance changes have been measured by changing the pressure and temperature. Hence, related to the effect of narrow space the critical pressure of supercritical CO2 is shifted to lower values. When the gap distance is shorter, the pressure of the minimum total-thermal-resistance becomes lower. This "narrow space effect" is enhanced by the shorter gap distance. Additionally, the change of thermal resistance related to pressure change is more responsive for narrower spacing. The smaller spacing seems to make more sensitive responsibility of the inserted fluid property. These results indicate that the filled fluid in a micro-chamber can be applied for the applications of sensing and switching devices using variable physical properties of the packaged fluid in narrow spaces.

    To detect cell healthies, mass and radical density of cell is an important role to monitor cell’s states. To measure the radical density in cell, the force measurement system is useful by detecting electron magnetic resonances. For higher sensitivity in air, vacuum packaged magnetic sensors and diamond nitrogen vacancy (NV) center on Si probes have been developed. The magnetic sensor showed the detectable magnetic field of 2.4×10-10 T. The probe with NV center is usable for magnetic detection using optical methods based electron magnetic resonance. To measure the mass changes of cell, an assembled micro-tube resonator for mass sensing in liquid is fabricated and evaluated. Flowing liquid is injected as the evaluation of mass change detection performance of the device. Self-oscillation experiment has been used for recording actual mass change based on the resonance frequency shift with flowing liquid. Minimum mass resolution of the device is in the value of 1.04 pg.

    Thermal sensors for the detection of tiny heat from a single biological cell in a solution have been developed using a microfabrication technique. This sensor utilizes the temperature dependence of the mechanical resonance, and heat transmits to the sensor by thermal conduction via a heat guide. The resonant sensor is thermally isolated from surronding area using vacuum isolation, thus the thermal loss is minimized. Scaling down of the sensor decreases the thermal capasitance of the sensor, which enhance the temperature response. Heat detection from a single cell is demonstrated using the developed thermal sensor.

    Thermionic power generation is one of clean sources, which directly converts heat into electrical energy using thermionic electrons. We developed a micro-gap thermionic power generator, which operates at relatively low temperature using SiC as an emitter.In this work, we have firstly demonstrated low temperature operation at 830 degree C as a result of micro-gap between the emitter and collector electrodes. An output power density of 11.5 mW/cm2 is obtained. Besides, the heat losses from the emitter electrode are evaluated and calculated. The thermal resistance of the micro-gap is measured to be 2.4 K/W. As a result,thermal conduction to the collector is by far the predominant thermal loss. It is needed for downsizing the silicon dioxide columns of the micro-gap in order to increase the power conversion efficiency.

    Nanowire cantilever sensors made of Si with a magnetic particle on the tip were fabricated for the study of bi-stable polymer material properties using magnetic resonance force microscopy (MRFM). The mirror part at the middle of cantilever was designed for interferometer to measure the deflection of the nanowire cantilever. Single NdFeB particle of 3.5 micron is mounted on the apex of the cantilever. The bi-stable polymer called PVBPT, which can hold radicals inside of the film after oxidation was used. The PVBPT sample was measured using the MRFM system, and the magnetic resonance force signals were detected by scanning the sample in XYZ directions. As the conclusion of this research, the potential of imaging the radicals in film or the defects on the surface of silicon by using high sensitive silicon nanowire probes is improved.
