A new strategy for the fabrication of a flexible and highly sensitive capacitive pressure sensor

Abstract The development of flexible capacitive pressure sensors has wide application prospects in the fields of electronic skin and intelligent wearable electronic devices, but it is still a great challenge to fabricate capacitive sensors with high sensitivity. Few reports have considered the use o...
