Abstract
Chemoresistive hydrogen gas sensor with zinc oxide (ZnO) thin film as a sensing layer has been studied with a coplanar integrated architecture of microheater and interdigitated electrode (IDE). ZnO thin films are fabricated via a chemical route. The present study is based on the use of a coplanar microheater with IDE’s fabricated for the hydrogen sensor. Further, the effect of the integrated architecture over sensing properties of the sensor has been studied. The sensing response of the sensor with film thickness of 150 nm at an operating temperature of 160 °C comes out to be 10.97. The prime aim of the study is to present coplanar integrated architecture of microheater and IDE’sfor a ZnO based hydrogen sensor.
