摘　　要：本文介绍一种高分子结露型湿度传感器,该传感器采用新型亲水性树脂作为感温材料,选择特殊结构.其阻值在低湿状态下几乎不随湿度变化;高湿时发生突变,阻值急剧上升,具有开关特性.该传感器可广泛应用于高湿及结露状态的检测与控制,诸如录像机、摄像机等视频产品配套.A dew sensor has been put into practical use through the development of a new hydrophilous resin and a manufacturing technique for uniform resistive film. The resistance of the sensor rises sharply, like a switch in high reletive humidity range, which makes it possible to detect a dewing state easily.
