Abstract
A compact system for optimizing energy harvesting efficiency using of very thin (less than 10 μm thickness) PVDF films. The system is comprised of a flexible substrate such as polypropylene (PP) or Polydimethylsiloxane (PDMS) that supports PVDF thin films sandwiched between two aluminum electrode sheets. The PVDF films may be fabricated at different selected thicknesses by increasing spin rates. The PVDF films may also be fabricated in various different stacking arrangements in order to further allow the electrode to more efficiently produce energy.
