▎ 摘　　要

NOVELTY - The method involves providing oxidation graphene solution on a substrate to obtain an oxidation graphene film. An electrode layer is arranged on a laser reduction oxidation graphene conducting layer for carrying out a photo-etching by using the oxidation graphene film. The electrode layer and the laser reduction oxidation graphene conducting layer are cut by using a laser reduction oxidation graphene fork. The oxidation graphene film is arranged on an electric conduction layer for manufacturing a pressure sensor by using the laser reduction oxidation graphene fork. USE - Pressure sensor preparation method. ADVANTAGE - The method enables realizing high sensitivity and detecting pressure by using the pressure sensor in an effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a pressure sensor.
