A taste sensor with global selectivity is composed of several kinds of lipid/polymer membranes for transforming information of taste substances into electric signal. The sensor output shows different patterns for chemical substances which have different taste qualities such as saltiness and sourness. Taste interactions such as suppression effect, which occurs between bitterness and sweetness, can be detected and quantified using the taste sensor. The taste and also smell of foodstuffs such as beer, coffee, mineral water, soup and milk can be discussed quantitatively. The taste sensor provides the objective scale for the human sensory expression. Multi-modal communication becomes possible using a taste/smell recognition microchip, which produces virtual taste. We are now standing at the beginning of a new age of communication using digitized taste.

This paper reports an actuation method of MEMS chiral metamaterial that transforms a two-dimensional MEMS spiral with diameter 150 µm to a three-dimensional spiral by individually pulling the center of spirals. The spiral dimension was designed to work in THz electromagnetic frequency. MEMS spirals were manufactured by bonding the central part of spirals and a Si wafer with Parylene bonding, and were deformed by lifting the Si wafer. It was confirmed that spirals were stably pulled by amplitude of 60 µm at the maximum by relatively separating the spiral and the Si wafer.

We have succeeded in developing a capacitive 6-axis force sensor that can singly detect 3-axis force and 3-axis moment. The capacitive 6-axis force sensor has an advantage of being able to realize high accuracy at low cost compared with conventional sensors using strain gauges. This paper details the sensor structure, detection principle, and detection circuit, as well as the performance, such as sensitivity, cross-axis sensitivity, and linearity of the capacitive 6-axis force sensor.

Parallel beam structure has many significant features, as follows. (i) The tip moves in parallel at the end. (ii)This structure converts the small displacement into the large strain. (iii) Each unit doesn't interfere to the other units by piling up this structures. We used this structure for piezoelectric vibrating gyroscope (angular rate sensor). In this paper, we analyzed features of the parallel beam structure by Finite Element Method, and showed that the resonance frequency of the drive unit and the sensor unit can be easily adjusted by changing the mass at the tip. From this result, this structure suits for the gyroscope. Experimental results are shown.

The taste of beer was measured using a taste sensing system with eight kinds of lipid membrane. The output from the sensor has high discriminating power and high correlation with taste substances in beer and sensory test by human. The estimation of the concentration of taste substances by multiple regression analysis was fairly well. The taste sensor also well estimated the result of sensory test of many keywords concerning beer taste.

In general, beer degradation is evaluated by sensory test, however it depends on the subjectivity of an inspector. Therefore, it is highly required that an objective evaluation method is developed. It has been clarified that the degradation degree of beer proceeds mainly by oxidation of components derived from malt and formation of non-electrolyte trans-2-nonenal. In this study, we developed LB film taste sensor using metal complex for evaluating the degradation degree of beer with trans-2-nonenal concentrations. In addition, the physical properties of three metal electrodes and sensing film surface were evaluated with AFM and FT-IR, and these results and the sensor response characteristics were compared and discussed for improving the sensitivity as a sensor for beer degradation evaluation.

The detection of accidents on elderly person living alone and the communication between the elderly person and his/her family are very important. This paper describes a new method for tracking and fall detection of elderly person using omni-directional image sensor, and the Itawari-kan communication system that supports their communications and gives alarms for detected accidents on the elderly person. This system tracks the person's head position in real-time by image processing on images captured by some omni-directional image sensor. Then, the system transmits the information of the detected head position to another site. The computer of recipient site generates the computer graphics animation of the tracked person and displays the animation on a monitor. When the system detects an accident from the head position, the system gives an alarm. This method reduces traffic on network and keeps the privacy for the tracked person. We made a prototype system of the Itawari-kan communication system. Experiments on the system showed good feasibility of the proposed system.

In this work, we have developed an alternative and improved “optical softlithographic” microfabrication method for patterning on a concave substrate as well as the fabrication of micro patterned PDMS cylindrical stamps for the potential application to nano imprinting. Firstly, we fabricated SU-8 micro patterns with high aspect ratio (over 4) on a concave glass substrate using optical softlithography, where UV light was exposed through a very flexible mask attached on the concave surface. We investigated the optimal experimental conditions depending on shapes and scales, and examined the resolutions of patterns. Next, we replicated a PDMS cylindrical stamp using SU-8 micro patterns as a mold. Intermediate female molds were made from the original cylindrical mold. Then, the stamp was made by filling the intermediate mold with PDMS monomer and solidifying it. Thus, this technique provides us with novel fabrication technique of 3D micro patterns on curved substrate as well as a cylindrical polymer stamp for roll micro contact printing.

<p>We measured flow speed of a moving object in a water with Doppler effect using a MEMS ultrasonic receiver. This measurement is aimed for non-invasive blood pressure measurement. We proposed a wide frequency range receiver to measure both blood flow speed and vessel diameter at the same time in a blood vessel. Our sensor has a piezoresistive cantilever which is put on the boundary between air and liquid in a device. According to this structure, proposed receiver can measure acoustic waves from Hz to MHz order frequency, so that we can obtain blood flow speed (MHz order), and blood pressure change (Hz order) with the same device. On this paper, we measured flow speed ranging from 64.0 to 76.3 mm/s with 5.6 to 19% error.</p>

The calibration procedures of charge amplifier (CA) on vibration acceleration standard are described. The calibration principle and fundamental calibration procedures are explained in detail. Typical commercial CAs (3 types, 4 CAs) are evaluated in terms of the frequency sensitivity gain, the long-term stability, the linearity for input charge, the linearity for gain setting and the effects of environmental conditions (temperature and humidity). The maximum discrepancy in the sensitivity gain is approximately 4 % among the tested CAs. A relative sensitivity gain difference of 1.5 % still remains when CAs of the same type are compared. It should be mentioned that a difference of 1.5 % is not negligible. Such a large difference has not been commonly observed up to the present time. Based on these experimental results, the technical guides for charge amplifier calibration are summarized.

<p>It has been suggested that the <i>Kansei</i> Multi-Media Display (KMMD) is able to emit air flows and scents in addition to conventional audio-visual information through the display. This display is characterized as follows: the display has slits and pits to emit air flows from a position close to projected pictures due to a system where the display is equipped in the back with an air blower and an air flow direction controller. This study aimed to show the psychological effects of two content layouts for cool refreshment, which were produced based on the characteristics of this multi-media display. The possibilities for function and application of the KMMD were examined. An experiment of a virtual fan created as a three-dimensional CG assessed the effects of cool refreshment and the feeling of presence induced by the air flows, which was connected to the swing movement of the fan and emitted from a position close to the image of the fan. Further, an experiment with seasonal images was conducted, providing aromas, which have been reported to affect an individual's sense of cold, when showing video scenes of a cold region. This experiment revealed cross modal physiological effects, such as the decline of the feeling of temperature and the temperature of the skin surface, which were induced subjectively and psychologically by the attribute of this scene.</p>

Voice recognition utilizing bone-conducted voice, which is very robust under noisy environment, has been investigated. The suitability for voice recognition and voice communication of bone-conducted voice recorded at several measurement points on human head was evaluated using LPC cepstrum distance (LCD) and Speech Transmission Index (STI). Experimental results show that forehead and cheek are good as the acquisition points of bone-conducted voice. In order to improve the quality of bone-conducted voice, a novel sensor, which has an inclined frequency response, was fabricated. Using the sensor, acquired bone-conducted voice has a similar frequency response as that of air-conducted voice. Spectral Subtraction is suggested as a method to improve the voice recognition ratio of bone-conducted voice.

This paper presents a novel QCM (quartz crystal microbalance) sensor for detecting interactions between membrane proteins and their ligands using liposomes derived from human cells. First, liposomes having BCR (B-cell receptor) were derived directly from cell membranes by stimulating human lymphocyte cells, Ramos, with NaB (sodium butyrate). Next, the liposomes were separated from the cells by filtration and micronized by sonication. Then, the liposomes were immobilized on the surface of a QCM sensor chip using cell-anchoring molecules. Several experiments demonstrated that ligand detection is achieved by frequency reduction with application of the antibody against BCR.

In this study, we propose a simple observation method of the shape and molecular orientation of the chromosomes extracted from cells for a sample-to-analysis system in clinical diagnosis. The proposed technique is composed of total preparation technique such as cell immobilization, chromosomes extraction, stretching, suspension and analysis using a disposable microchip controlled by centrifugal force only. It is experimentally confirmed that the chip having two kinds of microstructures arranged concentrically on a chip immobilizes cells and stretches chromosomes extracted from the immobilized cells.

This paper presents a cell compression stimulus microdevice intended to evaluate the real-time response of cells to compression stimuli. The presented device consists of cell inlet ports, a pressure inlet port, a gasket, microchannels, culture chambers, and a diaphragm on the culture chamber for applying compressive pressure to cells. Compression stimuli applied to the cells can be controlled by regulating the expansion of the diaphragm via a pressure control. The device permits the observation of cellular responses to compressive pressure in real time because it is made of transparent materials and stimulates the cells without deforming the cell culture surface, when observed by optical microscope. We observed the cellular deformation and response behavior using a fabricated microdevice in real time. The changes of intracellular calcium concentration before and after compressive stimuli were observed by the fabricated device. Also, the intracellular maximum strain part and strain distribution of a cell that received compression stimulus were clarified by FEM analysis. These results indicate the device is expected to clarify the cellular mechanoreceptor mechanisms and signal transduction pathways and facilitate the control of stem cell differentiation by a combination of the experimental results and FEM analysis results.

This paper reports part of a novel packaging method for a capacitive micromachined ultrasonic transducer (CMUT) based ultrasonic endoscope using low temperature co-fired ceramic (LTCC) side via architecture. An annular ring array CMUT device is designed and fabricated for packaging. LTCC is used as a prime wafer for CMUT fabrication and LTCC side via structure is achieved by hexagonal shape dicing of the fabricated CMUT device. A hexagonal shaped polyimide substrate mounted at the backside of the CMUT is used as a base layer for IC integration (flip-chip bonding) and also provides mechanical support to the CMUT. Cr/Au electrodes were patterned on the LTCC side via and polyimide substrate to achieve electrical connection between CMUT arrays and IC circuits. Au bonding pads were successfully completed on the polyimide substrate by electroplating for flip-chip bonding. Flip-chip mounting on the polyimide substrate is described and the electrical resistance of bumps is measured using the 4-probe method. The difference between the measured and calculated resistance is discussed. This method with the indirect connection of CMUT arrays and IC circuits has flexibility for high performance tube-shaped CMUT packaging with small diameters for intravascular imaging.
