When porous electrodes are placed on both sides of a zirconia ceramic, with one side exposed to the atmosphere and the other to exhaust gas, an electromotive force is generated in response to the oxygen concentration in the exhaust gas.
This characteristic can be utilized for air-fuel ratio control of exhaust gas.
