Abstract
A pressure sensor has a base layer, a supporting structure arranged on the base layer, and an elastic layer disposed above the base layer and the supporting structure. The elastic layer has a curved lower surface that is recessed away from the base layer. The curved lower surface, the supporting structure and the base layer define a cavity with an arched top wall. A first electrode, a second electrode, and an elastic body are all arranged within the cavity, such that when the elastic layer is elastically deformed in a direction of the base layer, the variable resistance elastic body electrically connects the first electrode with the second electrode, so as to generate a first signal related to the elastic deformation of the variable resistance elastic body.
