【Abstract】 A water-resistive humidity sensor was fabricated by using OH grafted organosili-conpolymer as sensing membrane. The resistance of the sensor decreased by five orders of magnitude with increasing relative humidity from 15 to 100%RH. The response time of these devices was about 10s for the abrupt change of humidity from 75 to 33% RH or from 100to 75% RH while one or two minutes was needed for the change from 33 to 75%RH or from 75 to 100%RH. The behavior of water resistive was good.更多还原
