Abstract
A pressure sensor includes a base having a bottom wall and a first sidewall enclosed with the bottom wall to form a first receiving space. A pressure sensitive film is located in the first receiving space and the peripheral portion of the pressure sensitive film is arranged on the first sidewall. An elastic cover has a top wall, a second sidewall, and a protrusion. The top wall and the second sidewall are enclosed to form a second receiving space. The second sidewall is located on the first sidewall of the base, the protrusion extends from the top wall to the second receiving space and makes contact with the pressure sensitive film, transferring an external pressure to the pressure sensitive film. The resistance of the pressure sensitive film is virtually linear corresponding to the external pressure.
