Abstract: In recent years, as an important module of smart wearable devices, flexible sensors have been continuously researched and applied in various fields. Among them, flexible fabric sensors use textiles as the carrier of sensing materials, which has greatly improved the application of flexible sensors in smart clothing. Based on the current research status of flexible fabric sensors, by reviewing related research, the pressure, temperature and strain sensors in flexible fabric sensors are mainly introduced, the preparation methods are summarized, and their principles, characteristics, and development trends are analyzed. Combined with the actual application prospects, existing problems at this stage of research and prospects for the development of flexible fabric sensors are discussed.
