Abstract

Research in flexible materials and conductive nanomaterials has advanced the development of flexible pressure sensors. These sensors combine flexibility while converting pressure into measurable electrical signals. Hence their value in areas such as artificial skin, medical detection, and human-computer interaction. This paper reviews the research progress of flexible pressure sensors in the past 20 years, focusing on piezoresistive, capacitive and piezoelectric types, and systematically describes their basic working principles, latest technological breakthroughs and practical applications. The study shows that piezoresistive sensors have achieved high sensitivity and wide detection range through the optimization of planar thin films, microstructures and 3D porous structures; capacitive sensors have significantly improved their response performance with the innovation of dielectric materials such as air and graphene; and piezoelectric sensors have a unique advantage in dynamic signal detection due to their self-powered characteristics. Looking ahead, these three types of sensors have great potential in human-computer interaction, medical and health monitoring, etc. Emerging features such as self-healing function and multifunctional integration provide new ideas for electronic skin and wearable devices, but the challenges of performance balance, environmental stability, and large-scale production still need to be further broken through.
