Abstract

Human olfactory is studied for a long time and in many ways, and many of them are based on gas chromatography technology. They have used gas sensors made of metal-oxide semiconductors. The semiconductor sensors can detect gases as difference in electric resistance by oxidation or reduction of surface on the sensor. Human olfactory is organized by about 2,000 receptors of smell, and many electric sensors are used to emulate the receptors. We consider applying multi-channel QCM for these sensors. However, QCM sensors in a chamber (small box) interfere with each other, and we should examine measures of a design method for anti-interference. In this paper, we propose a design method and build an evaluation system.
