摘要：
In order to promote the application of conductive composite fibers in the field of flexible strain sensors, the fabricating methods from the combination of the conductive material and the flexible matrix are reviewed. The flexible strain sensors are divided into 3 types, i.e. the conductive material/flexible matrix uniform composite fibers, the flexible fiber coated with a conductive material, and coated the conductive fibers using a flexible matrix. On this basis, the performance of these 3 types of conductive composite fiber sensors are compared and analyzed, and the sensing performance of various conductive networks are summarized. It is found that the strain property and sensitivity of the sensors are determined by the deformation behavior of fibers and the piezoresistive effect of the conductive network, that the interface interaction between the conductive material and the flexible matrix is the key factor to affect the stability and durability of the sensor, and that the fiber and fiber assembly with composite structures and multiple conducting network structures are conductive to the development of high-performance sensor. The application and development trend of conductive fiber flexible strain sensor are described, and the future research directions are put forward. © 2021, Periodical Agency of Journal of Textile Research.
