▎ 摘　　要

NOVELTY - The device has a cylindrical container (3) filled with low-pressure gas (4) for inwardly bending a circular silicon plate (1), where radius and thickness of the circular silicon plate are respectively for about 2 mm and 20 m. Two ends of a graphene film (2) are respectively connected with two ends of a bridge circuit, where length, width and thickness of the graphene film are respectively for about 1 mm, 500 microns and 0.35 nm. The circular silicon plate and the graphene film are bend towards an inner part of the cylindrical container under the low-pressure gas (4). A read voltage table obtains a pressure difference value of a circular center. USE - Graphene conductive characteristic based sealed container gas pressure measuring device. ADVANTAGE - The device changes length and resistance of the graphene film, extracts corresponding current and voltage signal of bridge circuit, collects change signal so as to obtain air pressure of vessel. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene conductive characteristic based sealed container gas pressure measuring device.
