Thermopile과 삽입된 $SnO_2$ catalyst를 이용한 NOx 센서

A NOx gas sensor based on thennopile and embedded tin oxide catalyst

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, the response time and recovery time were remarkably improved. The fabricated gas sensor was characterized through detecting NOx gas with various concentrations.
