▎ 摘　　要

NOVELTY - The device (A) has crumpled rGO (1) that is deposited between metal contacts (2) on a substrate (3). The size of crumpled rGO is ranging from 5 mu m to 10 mu m. The substrate is selected from a group consists of rigid glass, flexible substrates, and kapton. The pressure measured is air pressure below and above atmospheric pressure or water pressure. The rGO is optionally secured on four sides or two sides. USE - Sensor device for measuring pressure and strain. ADVANTAGE - The sensor device with sensing capacity over a wide range of pressures and strains can be achieved. The cost effective method of fabrication of the sensor device and the method of detecting the pressure and strains can be achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of fabrication of device for measuring pressure and strain. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the sensor device. Crumpled rGO (1) Metal contact (2) Substrate (3) Sensor device (A)
