▎ 摘  要

NOVELTY - The sensor has an insulating sheet located between a conductive sheet i.e. metal conducting strip, and a graphene conductive sheet, where thickness range of the insulating sheet is about 50-200 microns. The graphene conductive sheet is provided with a first graphene conductive unit and a second graphene conductive unit. A first protective layer is located on the conductive sheet away from a surface of the insulating sheet. A second protective layer is located on a surface of the graphene conductive sheet away from the insulating sheet. The insulating sheet is made of polyurethane. USE - Piezo-resistive film pressure sensor. ADVANTAGE - The sensor ensures resistivity of graphene lesser than resistivity of semiconductor silicon to ensure better conductive properties of the graphene conductive sheets so as to improve electrical conductivity of the piezo-resistive film pressure sensor. The sensor adopts single-layer carbon atom structure for graphene to reduce thickness of the graphene conductive sheet than thickness of the conductive sheet fabricated by silicon material so as to reduce thickness of the piezo-resistive film pressure sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a piezo-resistive film pressure sensor manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a piezo-resistive film pressure sensor.
