▎ 摘　　要

NOVELTY - The sensor has a sealing layer arranged with an elastic substrate layer and a net-shaped graphite pressure induction layer. The elastic substrate layer is provided with an induction area, a lap joint area and an electrode area. The graphite pressure induction layer is arranged between the electrode area and the lap joint area. A packaging layer is covered between the graphite pressure induction layer and the electrode area. Resistance of the graphite pressure induction layer is about 0.1-106 ohms per square. The electrode area is made of polymer film i.e. PI, PET, PE and PMM films. USE - Graphene pressure sensor for use in an intelligent mobile phone (all claimed). ADVANTAGE - The sensor has high sensitivity and high operating stability and prolonged service life, and reduces manufacturing cost. The sensor controls graphene pressure sensor preparing process in an easy and simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene pressure sensor preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene pressure sensor.
