Sensor for Detecting a Gas

摘要

A sensor for detecting a gas may include a transport layer for transporting ions, a first electrode and a second electrode spaced apart from one another by the transport layer, a heating device controlled by a voltage source, and a second voltage source applying a voltage difference across the electrodes. The transport layer may be conductive for the ions starting from a specific temperature. As a result of applying the voltage difference, ions stream from the first electrode through the transport layer to the second electrode if the first and second electrodes are in contact with the gas. The voltage source may provide a voltage potential of zero volts averaged over time or provide the voltage potential of the first electrode at the heating device.
