Modeling and Optimization of Graphene-PEN Based Flexible Piezoresistive Pressure Sensor (FPPS) for Enhanced Sensitivity

This paper presents a comprehensive study on the modelling and optimization of a graphene - polyethylene naphthalate (PEN) based flexible piezoresistive pressure sensor (FPPS). Leveraging the unique properties of graphene and PEN substrate, we achieve exceptional sensitivity in pressure detection. The analysis were done using COMSOL Multiphysics 6.0 version. The proposed sensor demonstrates significant promise for application in wearable electronics, healthcare monitoring and human machine interface.
