▎ 摘　　要

NOVELTY - Graphene pressure sensor comprises a cavity is processed on a polydimethylsiloxane substrate (1). A main electrode pair (2) and an auxiliary electrode pair (3) are arranged on the polydimethylsiloxane substrate and are respectively located on two sides of the cavity. The main electrode pair and the auxiliary electrode pair are both provided with leads. A graphene film (4) covers the cavity and the leads of the main electrode pair and the auxiliary electrode pair. The graphene film is tensioned by the recovery potential energy of the polydimethylsiloxane substrate. The cavity is formed by a reverse mode on the silicon chip. USE - Used as graphene pressure sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene pressure sensor.
