Abstract
The planar pellistor is a thin film microsensor used for the detection of inflammable gases. In its simplest, it consists of a metallic meander structure that serves both as a heater for the catalyst and as a temperature sensor. For low power operation thermal insulation between the sensor and the substrate is vital and is achieved by a thin silicon nitride membrane. The optimization of such a structure in terms of the sensor's dimensions is discussed.
