- Abstract
Flexible pressure sensors have received wide attention due to their potential applications in wearable electronics and electronic skins. It is still a challenge to manufacture high-sensitivity flexible pressure sensors in a low-cost and efficient way. In this study, a low-cost and simple method for preparing a flexible pressure sensor with porous structure based on physical foaming is proposed. The sensitivity of the flexible pressure sensor is 0.796 kPa−1 (applied pressure ≤ 2 kPa). In addition, the flexible pressure sensor has a low limit of detection of 4 Pa and a fast response time of 65 ms, and its performance remains unchanged after 1000 loading/unloading tests. This high performance enables flexible pressure sensors to detect touch and limb movement. Considering the good performance of the device, we expect that the sensor will provide broad application prospects in the fields of smart electronics and artificial intelligence.
