| Research Abstract |
Many works have been performed for realizing objective systems sensing odors or tastes by mimicking olfaction or gustation. The purpose of the present research project is to promote the discussion of the researchers in these fields and the realization of odor or taste sensing systems. In the first year (1991), two meetings were held, in which the project members described their studies and the present R&D situation of the sensing systems. Kurihara told the recent studies on olfaction and gustation, Okahata the partition coefficients of bilayer lipid materials to odor gases and their dependences on odor molecular structures, Moriizumi the systems composed of quartz-crystal resonators with odor adsorption films and gas flow network and the odor identification by the output pat- terns of the sensors, and Tokyo the taste sensing systems where tastes are recognized by the potential output patterns of the electrodes coated with various kinds of lipid materials. Yoshikawa reviewed the instbil

ity appearing at an oil-water interface and its application to chemical sensing, and Kawakubo, Sawada and Moriizumi told their recent studies on that phenomena. Other reports on how to improve the characteristics of semiconductor gas sensors were made by Sirae, Hiranaka and Moriizumi, on the biosensors using semiconductor surface photovoltaic effects and surface plasmon waves by Katsube and Shiokawa, and on the chemical sensors with multi-fluorescence spectra by Aizawa. Three meeting were held in the Second year of the project, 1992. Aihara reviewed a basic aspect on chaos and its role in neural-network information processing, and Yamazaki the sensor fusion technology by which several perception informations are unified to obtain a total structure of in formation. The experts outside of the project were quite cooperative to this project; i.e., a basic survey on olfaction and the studies of olfactory responses appearing in electroencephalogram (EEG) were reviewed by Aihara, the materials and chemical structures of odors, lingual description of odors and its training methods for panelors were described by Wachi, and finally the neurophysiological studies on silk-worm feromone reception were lectured by Kanzaki. These two-year project gave us much information on olfactory and gustatory reception mechanisms and big impacts for promoting the R&D studies on artificial odor or taste sensing systems. Less
