Highly-Sensitive Graphene-based Flexible Pressure Sensor Platform

Abstract

In this work, graphene has been utilized as the sensing material for the development of a highly-sensitive flexible pressure sensor platform.It has been demonstrated that a graphene-based pressure sensor platform that is able to measure pressure change of up to 3 psi with a sensitivity of 0.042 psi -1 and a non-linearity of less than 1% has been accomplished.The developed device, which resides on a flexible platform, will be applicable for integration in continuous wearables health-care monitoring system for the measurement of blood pressure.
