Abstract
Disclosed herein is a piezoresistive pressure sensor, including: a continuous piezoresistive foam layer; an electrode array layer, on one side of which the continuous piezoresistive foam layer is disposed; and an artificial leather layer as cover layer, which is disposed on the continuous piezoresistive foam layer; where the continuous piezoresistive foam layer is made by doping the foam with conductive materials. The piezoresistive pressure sensor can provide overall 2D-pressure mapping in a large area and has good flexibility and reliability to be combined with soft surfaces.
