Abstract
A micro-deformable piezoresistive material is provided, including a hard plastic body, a micro-deformable rough texture surface, and a plurality of conductive particles. The micro-deformable rough texture surface is formed on a side of the hard plastic body, wherein the maximum deformation of the rough texture surface is far less than the thickness of the hard plastic body. Additionally, the conductive particles are evenly dispersed in the plastic body.
