Abstract

This paper reports a novel gas sensing method by using a thermoelectric device, thermopile in this case, with an embedded tin oxide catalyst. By using a thin catalyst film and gas adsorption process instead of absorption, the response time and recovery time were remarkably improved. And the fabricated sensor was characterized through detecting a hydrogen gas. Finally, NO _x gas was successfully detected by using the proposed sensor. The respond and recovery time were shorter than 1 minute. The output signal change according to the concentrations of the NO_x gas was 1.5 x 10 ¹ μ V/ppm.
