what is reason for preferring platinum in micro-heater fabrication in the case of a gas sensor ?
my understanding is that it is because of its stability in different chemical environments. Please comment if there are any other reasons
 
I got the answer from some literature. firstly, Pt is stable in most of the chemical environments when compared to many other metals . secondly, power consumption in this case is less
thanks
