In this paper, we presented the design and simulation results of a platinum meander–spiral combination micro heater for a zinc oxide (ZnO) gas sensor. As a first step, different optimizations have been performed using a finite element analysis in order to obtain a compromise between maximum temperature, maximum homogeneity in active area and minimum power consumption. In the other hand, the effect of ZnO sensitive layer was studied.
