Abstract
A pressure sensor includes: a base substrate including an embossed pattern; a first conductive layer disposed on the base substrate; a pressure sensitive material layer disposed on the first conductive layer such that its electrical characteristic is varied corresponding to a strain applied thereto, the pressure sensitive material layer including a dielectric and nanoparticles dispersed in the dielectric; and a second conductive layer disposed on the pressure sensitive material layer, wherein the dielectric and the nanoparticle include materials having pyroelectricities of polarities opposite to each other.
