A Flexible Pressure Sensor Based on Bimaterial Conductivity-Conversion Mechanism

Flexible pressure sensor with excellent sensing performance and wearability is a major research focus for wearable electronic devices. In this study, polyporrole (PPy) wrapped cotton pads and silver coated wrinkle papers are stacked together to construct a novel piezoresistive sensor, and a bimaterial conductivity-conversion mechanism is presented. The PPy-cotton pads are prepared by an in...
