Abstract

This paper presents a low voltage graphene field effect transistor (GFET) based pressure sensor. The sensor comprises of GFET connected with a piezoelectric Aluminium Nitride (AIN) capacitor in an extended gate configuration. In this configuration, the piezopotential generated across the AlN capacitor, as a result of applied pressure, appears at the gate terminal of GFET and modulates the channel current. The sensor operates at a remarkably low voltage (100 mV) and exhibits a sensitivity of about 7.18×10 -3 Pa -1 for a pressure range of 3.25-9.74 kPa. These values make the developed GFET sensor suitable for tactile skin in robotics and prosthetics and for wearable health monitoring devices.
