MISiCFET sensor arrays for on line diagnosis

Catalytic Metal Insulator Silicon Carbide Field Effect Transistor (MISiCFETs) sensors can be processed as a sensor array on a SIC-chip. Different selectivity of the sensors is achieved by the use of different combinations of catalytic metals and insulators. The response patterns are used to evaluate for example different states of a combustion (low/high emissions, efficient/less efficient combustion) or monitoring different components in the exhausts from the combustion.
