When porous electrodes are placed on both sides of zirconia ceramics, with one side exposed to the atmosphere and the other to exhaust gas, an electromotive force is generated according to the oxygen concentration in the exhaust gas.
By utilizing this characteristic, it can be applied to air-fuel ratio control of exhaust gas.
