MODEL OF THERMAL TRANSIENT RESPONSE OF SEMICONDUCTOR GAS SENSORS

Akira Fujimoto

1. INTRODUCTION

There are variety of needs to detect specific gases and smells for monitoring in food processing, to measure olfactory pollution, and so on, as well as to monitor gas leakage. Although the necessity to measure the strength and the kind of a smell is becoming large, there are no handy smell identification sensors. At present, we have to use gas chromatography for measuring smell concentration and smell identification.
