Abstract

At present the artificial lipid films, ZnO, SiO<SUB>2</SUB> and etc. have been utilized for the electrical measurements on taste or odor of various foods. The electrical property of a Mn<SUB>x</SUB>Zn<SUB>1-x</SUB>Fe<SUB>2</SUB>O<SUB>4</SUB> composite metal oxide thin film (CMF) changes depending on a sort of a molecule and an ion absorbed physically on its surface, so it could be applied to the taste sensor. We investigated application to the drink recognition sensor of the CMF and constructed Drinking water Recognition System (DRS). The films with 1.5 μm-thickness is prepared on Al<SUB>2</SUB>O<SUB>3</SUB> substrate by the sputtering method and the subsequent annealing process. The multi channel recognition system combined with the plural sensors having different electrical properties by the preparation conditions can be clearly distinguished the kinds of drinking waters from output patterns. In this paper, the construction of the DRS and the recognition results for various drinking waters by DRS are discussed.
