Recent progress of sensor devices and materials: Especially in the intelligent applications

Sensor technology is now driving the development of intelligence in various fields. This review focuses on the mechanism, materials, performance, and intelligent applications of four representative kinds of sensors: resistive sensors, capacitive sensors, photodetectors, and triboelectric sensors. The intelligent applications of these kinds of sensors are reviewed emphatically, such as applied the sensors for internet of things, big data, artificial intelligence, and human-machine interaction. In addition, the review delves into the advantages, characteristics and challenges of each kind of sensors and relative materials, emphasizing their ability to interface diverse applications. This review also discusses how these sensors can be used to meet the needs of various application areas, thus facilitating the realization of smart functions. Insights into potential future challenges and development trends in the field of sensor devices and materials is offered. The objective is to provide researchers in related disciplines with comprehensive and in-depth references, thereby facilitating continuous innovations and broad applications of sensor technology in the artificial intelligence era.
