▎ 摘  要

NOVELTY - The sensor has an insulation dielectric layer (103) separating and holding first and second graphene electrode plates (102, 104) at predetermined intervals. The graphene electrode plates comprise two series of graphene electrodes. The two series of graphene electrodes of the graphene electrode plates are cross-arranged. Other oppositely facing graphene electrodes are located at an intersection of the first graphene electrode plate and the second grapheme electrode plate. USE - Capacitive pressure sensor. ADVANTAGE - The sensor allows the graphene electrodes of the graphene electrode plates to be crossly arranged and conductive electrodes of the electrode plates to form capacitance between intersecting positions, so that the sensor can quickly locate the first electrode plate and the second electrode plate according to a position of a touch and pressure sensing accuracy of a touch screen of the sensor can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a capacitive pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a capacitive pressure sensor. Flexible substrates (101, 105) Graphene electrode plates (102, 104) Insulation dielectric layer (103)
