ジャーナル フリーMEMS (microelectromechanical systems) ultrasonic sensors were fabricated using a polyvinylidene fluoride-trifluoroethylene (P(VDF/TrFE)) copolymer thin film on multilayered diaphragm structures. We developed a new diaphragm structure to improve the sensitivity through lowering the stiffness of the vibration part of the sensor compared to the conventional ones. The new sensor structure improved the sensitivity up to about 5 times compared to conventional the ones. Fabricated sensors with the new structure showed their sensitivity, resonant frequency and Q-value as -74 dB (1V/Pa = 0 dB), 89.2 kHz and 24, respectively.抄録全体を表示PDF形式でダウンロード (1092K) -

ジャーナル フリーParticulate Matter 2.5 (PM2.5) is known to be a dangerous substance that causes various diseases. In this study, same-time detection of PM2.5 and location data was realized using a PM2.5 sensor, microprocessor board, and Android portable device. An Arduino compatible microprocessor board was used to read analog and digital data of PM2.5 sensors. Sensor output was measured by an Android portable device to display real-time PM2.5 concentration value. The device also received local data by Global Positioning System (GPS), then it stored as a CSV format log file in the memory. The PM2.5 data was compared with commercially available PM2.5 instrumentation in the smoke chamber. The data showed linearity, but a sensitivity correlation was necessary for each sensor device. Furthermore, viewer software was used to make a PM2.5 heat map and time-series graph. The visualization helps users to check environmental PM2.5 levels and hot spots in contaminated areas.抄録全体を表示PDF形式でダウンロード (1246K) -

ジャーナル フリーDielectrophoretic impedance measurement (DEPIM) is a method to detect bacteria in an aqueous solution. DEPIM consists of two simultaneous processes: dielectrophoretic trapping of the target bacteria onto a microelectrode and measurement of impedance change caused by trapping bacteria. In this study, a new bacterial concentration process was combined with DEPIM to improve its sensitivity. The concentration process was based on negative dielectrophoresis of bacteria caused by specific configuration of parallel electrodes. A ditched dielectric thin layer deposited on one of the parallel electrodes causes non-uniform electric field resulting in occurring negative dielectrophoresis. Two electrode configurations, one is for the bacteria concentration and the other is for DEPIM, were fabricated in a microchannel. As a result, the detection sensitivity of DEPIM increased about 1.6 times by combining the concentration.抄録全体を表示PDF形式でダウンロード (2756K) -

ジャーナル フリーAn intraluminal magnetic resonance imaging (MRI) probe holds promise to achieve a higher resolution image of a small pathological lesion than conventional external probes. Such an intraluminal probe requires precise resonant frequency tuning to 63.865 MHz and impedance matching to 50 Ω, if used for instance in a 1.5-T scanner. Tuning and matching have to be performed after inserted into the subject body as electric permittivity varies according to the tissue location. Thus, in this study, a novel intraluminal MRI probe which can be tuned and matched remotely by voltage-controlled, MOSFET-type variable capacitors was developed and fabricated. The imaging capability and signal-to-noise ratio (SNR) was evaluated in an agar phantom.抄録全体を表示PDF形式でダウンロード (1844K) -

ジャーナル フリーStability of emulsion is an important index for quantitative assessment of cosmetics. In this study, we developed a portable sensor system equipped with a disposable type sensor chip which was made by a glass substrate with Cr electrode. Then we also determined the electric conductance of O/W emulsion of 5µL for 10s using the sensor system. On the basis of these results, we proposed the evaluation method of emulsified state for cosmetics.抄録全体を表示PDF形式でダウンロード (1434K) -

ジャーナル フリーThe development of an evanescent wave optical fiber sensor modified with an organic-inorganic hybrid nanoporous thin film for the detection of organic solvent vapors was demonstrated. The optical fibre with a core diameter of 200 µm was bent into U-shape to enhance the penetation depth of light transferred into the evanescent filed, and modified with a multilayered thin film of poly(allyamine hydrochloride) and silica nanoparticels, (PAH/SiO2)n, via layer-by-layer (LbL) film deposition. The mesoporous film structure led to higher molecular diffusion and the highest selectivity to methanol among the six alcohols and water, which were used as target analytes, by the aid of tetrakis(4-sulfophenyl)porphine (TSPP) infused inside the film.抄録全体を表示PDF形式でダウンロード (721K) -

ジャーナル フリーMetamaterial absorbers with various sizes were experimentally demonstrated in the terahertz frequency region, and their absorption characteristics were evaluated. They consist of an Au ground plane, a polyimide layer, and Au metamaterial structures. Two types of metamaterial absorbers with crossed shapes and cut-wire shapes were fabricated respectively. For both types of metamaterial absorbers, 90% of absorption was experimentally obtained around 1.5 THz frequencies.抄録全体を表示PDF形式でダウンロード (1945K) -

ジャーナル フリーWe aimed to develop taste sensor for evaluating hot drinks using several metal oxide films (ZnO, SnO2, WO3 and In2O3) as a sensing film. The films were formed using Pulse Laser Deposition method on Pt/Ag electrode. We measured the sensor responses for saltiness (NaCl), sweetness (Glucose), and mixed solution of saltiness and sweetness at 60 degrees. We observed the different responses from each sensing film. In these results, all developed sensors responded depending on saltiness concentration and the response value differed by kind of sensing films. On the other hand, it was shown that sensors can detect high concentration sweetness. These results suggest that our developed sensor have a capability to detect taste components and taste interaction in hot drinks.抄録全体を表示PDF形式でダウンロード (706K) -

ジャーナル フリーAn ultrasmall-capacitance-variation detector was developed that consists of a VHF-band LC oscillator and sensing pads. An oscillator frequency (～100 MHz) in the VHF band allows a small base capacitance to be used for resonance, which provides a high sensitivity to small changes in capacitance up to the attofarad level. A superheterodyne system is added to the LC oscillator to convert the VHF signal to 2 MHz range. A low power CMOS device, which requires 20 mW range, can be used to handle the 2 MHz signal, while high power CPLD such as 300 mW is required for the direct count of VHF signal. This conversion system saves 280 mW dissipation and contributes to achieve the battery operation of the sensor. As an application of the sensing system, a wireless sensor for the non-invasive detection of pests inside wood was demonstrated.抄録全体を表示PDF形式でダウンロード (2506K) -

ジャーナル フリーA nW-power-level automatic switch with two LED photovoltaic cells has been developed. The switch that has a sleep/wake-up circuit with LEDs automatically turns on when one of LEDs is shaded by hand in bright place. A nW-power-level automatic sleep circuit composed of a tactile switch and RC delay element has also been developed to perform switching operation in dark place. The tactile switch wakes up at one click motion and then the RC delay element that includes a zener diode automaticaly turns off after a constant time. We applied the automatic switch to a wireless mouse to verify the effectiveness of our circuit.抄録全体を表示PDF形式でダウンロード (1526K) -

ジャーナル フリーIn this study, we developed a novel taste sensor with Langmuir Blodgett (LB) films for evaluating the quality of Japanese sake. The sensing films were made of stearic acid (SA), DODABr and lanthanides coordinating with SA (Ln-SA), specifically, Tb-SA and Eu-SA. We measured electrical potentials of three different kinds of Japanese sake by the developed sensors. As a result, we obtained the different responses from each sensor. In addition, these results showed that the Ln-SA films enhanced the sensitivity of taste sensors with LB films to Japanese sake. This study indicates that Japanese sake of different manufacturing processes are discriminated by principal component analyses for developed sensor responses, and the modification of LB film materials makes it possible to develop high sensitivity taste sensor systems for evaluating the quality of Japanese sake.抄録全体を表示PDF形式でダウンロード (967K) -

ジャーナル フリーWe have been studied the light addressable amperometric sensor (LAAS) using an organic device since it has advantages in cost, flexibility, and large sensing area. However, it can be expected that the LAAS device using an inorganic semiconductor has high-durability even under severe conditions. We will demonstrate the array of amperometric sensors with discrete electrodes on Schottky junctions or pn junctions of Si wafer.抄録全体を表示PDF形式でダウンロード (970K) -

ジャーナル フリーThis paper shows that an experimental study of the Braitenberg's vehicle-like gas tracking robot with nonlinear sensor-actuator connection. The sensor-actuator connections which drive the robot in a gas tracking operation can extend by using a nonlinear elements for limiting the search area to avoid sensor saturation. The results show that the developed odor tracking robot which has nonlinear connection weights based on the sigmoid function can move to track the limited plume for sensor saturation.抄録全体を表示PDF形式でダウンロード (1283K)
