Abstract

In a gas sensor with at least two electrodes and with a sensor body which is connected thereto and is composed of a gas-sensitive material, in addition to pores which may already be present, second cavities are provided in the sensor body. The second cavities may be suitable on account of their size to facilitate and accelerate the distribution of gas molecules in the sensor body and to thus improve the time response of the gas sensor.
