Abstract

Gas sensor, including a membrane and a heating element arranged on the membrane between a first discontinuation area of the membrane and a second discontinuation area of the membrane. The first discontinuation area of the membrane includes at least one discontinuation of the membrane and the second discontinuation area of the membrane includes at least one discontinuation of the membrane. The gas sensor further includes a first temperature sensor structure arranged at least partially on the membrane on a side of the first discontinuation area of the membrane opposite to the heating element, and a second temperature sensor structure arranged at least partially on the membrane on a side of the second discontinuation area of the membrane opposite to the heating element.
