湿敏元件及湿度传感器在传感器技术中是一个相对弱小的分支。上个世纪末,湿敏技术市场在我国一度很不明晰,对湿敏传感器产业化的拉动作用很微弱。一度曾被看好的两大块市场:录像机(结露传感器)中途夭折了;气象领域又因技术、成本等问题而迟迟没有进展。而确实需要应用湿敏技术的纺织、轻工等行业,也因为行业调整、产权制度改革等更迫切的问题,而没有把用电子信息技术进行改造、提升纳入议事日程和普遍运作起来。所以湿敏技术市场多年来一直“热”不起来,湿度传感器的产销量也处于徘徊不前的状态。我国湿敏传感器的应用与市场现状进入21世纪后,特别在我国加入 WTO 后,我国传感器市场有了明显的变化,湿度传感器的市场也逐渐明晰,正处于快速发展阶段。除了以往传统的工控领
Humidity sensors and humidity sensors are relatively weak branches in sensor technology. At the end of the last century, the moisture sensitive technology market was once very unclear in China, and the pull of the humidity sensor industry was weak. At one point, the two big markets that had once been favored: video recorders (condensing sensors) died in the middle; the meteorological sector had yet to make progress due to technical and cost issues. Indeed, industries such as textiles and light industry that require the application of moisture sensitivity technology also have more pressing issues such as industry adjustment and reform of the property rights system. They have not adopted electronic information technology for transformation and promotion on the agenda and are generally operational. Therefore, the moisture sensitivity technology market has been “hot” for many years, and the production and sales of humidity sensors are still stagnant. After the application and market status of China’s humidity sensors entered the 21st century, especially after China’s accession to the WTO, China’s sensor market has changed significantly, and the market for humidity sensors has gradually become clear and is in a stage of rapid development. In addition to traditional industrial control
