PREPARATION AND CHARACTERIZATION OF MICROSIZE Fe DOPED RGO/PVDF PIEZOELECTRIC MATERIAL: A SMART APPROACH FOR ENERGY HARVESTING

Abstract

Piezoelectricity is an important property that can be used for generation of electricity from external mechanical force. One of the most widely used piezoelectric polymers for generation of electricity is PVDF. In this project the important properties of Polyvinylidene fluoride, graphene oxide and iron were utilized and an optimum composite was made for harvesting energy, PVDF for its high piezoelectric property, graphene for its conductivity and mechanical properties and iron dust for its high conductivity. The amount of RGO and Fe was varied till an optimum amount of energy was harvested. Finally an optimum voltage of 0.93V was obtained, which was further brought into use for illuminating a LED. The LED was gown with the help of charge and voltage amplifying circuit. Now, the same circuit could also be used for other low power electronic devises like buzzers, ear phones, etc.
