Abstract
Self powering implanted devices have been the main goal for most miniature device. Harvesting bioenergy is a remarkable method that can utilize a natural energy such as heart beat by converting the mechanical energy into electric power that can charge or even power implanted devices such as pacemaker. To achieve this goal, piezoelectric materials are used . This project is demonstrated as a novel idea of using dual layers Nano-scale film of polyvinyildin defloride (PVDF) and Graphene composite laying on each others that are embedded into self curling biocompatible silicone. The assembly converts mechanical actions of a blood artery (pulsated pressure of expansion and contraction) into corresponding voltage. Each PVDF\ Graphene layer has dimension of Wp=8mm,Lp=28mm,and Hp=17μm. Additional, the Nano film can be attached to vibrating transmitting plate for harvesting heart beat energy and Encapsulating the whole device with a biocompatible material.
