Investigation of PVDF-TrFE nanofibers for energy harvesting

We have investigated the copolymer polyvinylidene fluoride, (PVDF-trifluoroethylene) for energy harvesting. Polyvinylidene fluoride (PVDF) nanofibers were electrospun on indium tin oxide (ITO) coated plastic. The electrical response of nanofibers at different frequencies was investigated. The experimental results demonstrate that the duty cycle of electrical response pulses is increased as the frequency of vibration is increased. By using the fast Fourier transform (FFT) of the response pulses, the maximum power extracted has been calculated.
