Research progress in flexible wearable pressure sensors based on electrospinning nanofibers

Abstract

The flexible wearable pressure sensor has unique properties such as high comfort, strong braid ability and the ability to imitate human skin to sensitively perceive and respond to external stimuli. It can be used as the artificial electronic skin which will be widely applied in medical detections, disease diagnosis, human motion tracking and health monitoring, etc. In recent years, the design, construction, performance exploration and development of flexible wearable pressure sensors have attracted extensive attention from researchers. The nanofibrous membranes prepared by electrospinning have the advantages of high porosity, large specific surface area and easy to be functionalized, which make them have extensive applications in the field of flexible sensors. The research and progress of electrospun nanofibers in flexible wearable pressure sensors were reviewed in this paper. The major characteristics of the wearable pressure sensors were briefly introduced, and the advantages of electrospinning technology and electrospinning nanofibers in the preparation of flexible wearable pressure sensors were described. The types and applications of the flexible wearable pressure sensors based on electrospinning in different fields were emphatically discussed. Finally, the low-cost manufacture of flexible wearable pressure sensors with high resolution, high sensitivity and accurate response was briefly summarized and prospected.
