在众多的测湿技术中,电测湿技术是当今世界各国研究的重点。电湿敏元件是电测湿技术的基础。自1938年世界上第一个电湿敏元件——Dunmore元件问世以来,特别是近二十年来,由于湿度测量和控制的应用遍及国民经济的各个领域,造就了一个采用不同感湿材料、不同制造技术、适应不同要求的、品种繁多的电湿敏元件世界。电湿敏元件如何分类,至今尚无统一的意见。按所用感湿材料的不同,电湿敏元件可以分为:电解质系、高分子胀缩物系、高分子电介质

Among the many moisture measurement technologies, the technology of electrical measurement and wetting is the focus of research in various countries around the world. Moisture sensor is the basis of electrical measuring wet technology. Since 1938 the world’s first electrosensitive element - Dunmore components come out, especially in the past two decades, due to the application of humidity measurement and control in all areas of the national economy, has created a different use of wet materials, different Manufacturing technology to meet different requirements, a wide variety of electrical moisture sensitive components world. How to sort electrical moisture sensors, there is no uniform opinion so far. According to the wet material used by the different, moisture-sensitive components can be divided into: Electrolyte, polymer expansion and contraction system, polymer dielectric
