Fabrication of Stretchable PVDF Piezoelectric NanoGenerator

Abstract

    A piezoelectric layer process of heighten plasticity lightweight besides firstly self-controlled using one topic persistent in electrospinning technique. Piezoelectric layers device shows a three-layer assembly that PVDF. The poly (vinylidenefluoride) nanofiber layer fabricated to be between two Aluminum layers foil as electrodes as a sandwiched shape.  Then the completed generator was totally coated by a thin layer of polydimethylsiloxane (PDMS) to keep it in situation of packaging a device. Here, established highly piezoelectric in which flexible layers and increased the output voltage from (600 -800 mV) by using the same force and frequency. The fiber layer of structure crystal for PVDF was characterized by using XRD in range between (5-35°), FTIR in range between (500– 4000) cm^-1, and using liquid nitrogen for cross sections by wetted the three membrane layers of the device in addition beforehand imaging (SEM) the samples coated by gold as a thin layer. Finally by means of oscilloscope the output voltage for devices were indicated on behalf of piezoelectric membrane.
