Abstract:
A gas sensor for determining gas components in gas mixtures, e.g., for exhaust gases of internal combustion engines, includes a housing and a sensor element configured as a field effect transistor which has source, drain, and gate electrodes applied on a semiconductor substrate. A porous, catalytically active material is provided inside the housing of the gas sensor.
