A novel graphene pressure sensor with zig–zag shaped piezoresistors for maximum strain coverage for enhancing the sensitivity of the pressure sensor

The demand for flexible and wearable sensors is increasing day by due to varied applications in the biomedical field. Especially highly sensitive are required detection of low signal from body. It important develop a pressure sensor that can convert maximum input into electrical output. In this paper, design performance graphene piezoresistive have been investigated zig–zag piezoresistors on square diaphragm. On applied pressure, deformation sensed above Finite element analysis carried out investigate effect Simulated results optimized obtained an operating range 0–100 psi sensitivity.
