Humidity sensor made of metal oxide

A sintered body for a humidity sensor is formed by baking a blend at 1,000 DEG to 1,400 DEG C., the blend comprising ZnO, Cr2O3, V2O5 and M2O where M2O is at least one metal oxide selected from Li2O, Na2O and K2O. A pair of electrodes are each attached to the corresponding surface of the sintered bo...

Summary:A sintered body for a humidity sensor is formed by baking a blend at 1,000 DEG to 1,400 DEG C., the blend comprising ZnO, Cr2O3, V2O5 and M2O where M2O is at least one metal oxide selected from Li2O, Na2O and K2O. A pair of electrodes are each attached to the corresponding surface of the sintered body to obtain a humidity sensor of metal oxide which is relatively low in its resistive value and stable in its aging characteristic.
