柔性湿度传感器敏感材料与构型设计研究进展OA

To systematically sort out the technical framework and developmental lineage of flexible humidity sensors,the core structural categories and operational principles were outlined,focused on analysing the signal conversion mechanisms and response characteristics of mainstream capacitive and resistive humidity sensors.Subsequently,the research progress in three core humidity sensitive materials was reviewed,including carbon-based materials,polymer materials and metal oxide materials.The properties and application compatibility of one-dimensional,two-dimensional and three-dimensional flexible substrates were summarized.The typical applications of flexible humidity sensors in respiratory monitoring and non-contact human-computer interaction were analyzed.Addressing the core challenges in current industrialization,including insufficient stability,poor environmental adaptability and immature large-scale fabrication processes,the research directions of future flexible humidity sensors was pointed out.It is considered that in future,flexible humidity sensors should be focused on breaking through technologies such as multi-functional integration,low-power design and cross-scenario adaptation,which could promote the development of flexible electronics industry towards high performance,greening and intelligence.
