【Abstract】 Humidity sensors are widely used in meteorological monitoring, agriculture, medical treatment, food quality monitoring,industrial control and other fields. The organic polymer-based MEMS humidity sensors have excellent performance in the aspects of sensitivity, easy integration and humidity sensitive range. In this review, the principles and structures of different MEMS humidity sensors based on organic polymers are discussed. Meanwhile, the research progress of these humidity sensors in recent years is summarized. In addition, the influence of metal oxides, noble metal nanoparticles and 2D materials on performance of the humidity sensors are systematically discussed when these material are implanted into the organic polymers. Finally, the key issues hindering further development and practical applications of the humidity sensors are put forward, and the future development directions are discussed.更多还原
