Gas sensors operated with a small battery is an exciting objective. The authors tried it with a thin film SnO{sub 2} semiconductor as a sensing element and IC-technics, and the other with a sintered SnO{sub 2} and various pulse driving methods. These tries have both advantages and disadvantages. Thin-film sensors suffer from low stability and low sensitivity to certain gases. SnO{sub 2} sensors have more favorable operating characteristics, but they require much power and have long response times. The authors corrected these shortcomings with good success through miniaturization of a SnO{sub 2} sensor.
