This article presents a novel framework of image sensing based on the time-domain correlation image sensor. The correlation detection mechanism of the sensor realizes pixel-parallel, selective detection of wide-band modulated optical patterns at an ordinary frame rate, which cannot be achieved by conventional image sensors. This remarkable feature allows a variety of real-time imaging applications that employ powerful techniques of correlation detection.

The top silicon layer of single-crystal silicon-on-insulator wafer is used to fabricate flexible membrane for a deformable mirror. Boron implantation was carried out to control the stress of the silicon membrane. In the case of 415μm diameter 1μm thick mirror, the deflection of 320nm was generated due to the bending moment at the rim. After the implantation, it decreased to 120nm deflection by the increased of tensile stress. Moreover, etching the membrane from the thickness of 1μm to 480nm. The deflection decreased to 20 nm and the flat region of mirror increased to 300μm in diameter.

An antigen-antibody sensor consisting of a silicon-based chip contains a mixture of poly[ethylene glycol] (PEG)-grafted single-walled carbon nanotubes (PEG-SWCNTs) and SWCNTs modified with an antigen by using plasma ion irradiation (plasma activation) method , was developed. According to X-ray photoelectron spectroscopy (XPS) analysis, peaks which correspond to CO and COOH radicals increased in impedance due to BSA/anti-BSA binding. The results of this study indicate that this antigen-antibody sensor reacts with a quick response time.

A taste sensor is composed of several kinds of lipid/polymer membranes as transducers which convert taste information to electric signal. Thus, the role of membranes is very important to detect various taste components. In this paper, we developed novel membranes which specifically respond to quinine that is typical bitter substances. These membranes were composed of hydrophobic ionic liquid such as N, N, N-trimethyl-N-propylammonium bis(trifluoromethansulfonyl)imide, 1-butyl-3-methylimidazolium hexafluorophosphate and 1-butylpyridinium hexafluorophosphate, a plasticizer, 2-nitrophenyl octyl ether and a polymer, polyvinyl chloride. In addition to quinine, they also showed response to both several kinds of alkaloids such as caffeine and strychnine, and non-alkaloid such as phenylthiocarbamide. The order of these responses was equal to that of the tongue glossopharyngeal nerve of flog. Furthermore, there were the other alkaloids which response to these membranes. Especially in these alkaloids, they showed high response to denatonium benzoate and berberin chloride which have a strong bitter taste.

A clockwise rotor and a counterclockwise rotor are linked on the optical axis to control the rotation direction by displacing the trapping position. The optical torque of the linked rotor is analyzed for upward-directed focused laser illumination using a ray optics model, under the condition that laser light is incident to not only the lower surfaces but also the side surfaces of both rotors. The trapping position is estimated to be 1.1 μm up the center plane of an SU-8 double rotor (20 μm diameter, 10 μm thick, 3.3 μm wing width) with a laser power at 200 mW via an objective lens with a numerical aperture of 1.4.
