Fabrication of Piezoelectric Nanogenerators Based on Spin Coating of PVDF/ZnO Composite Film

Abstract

We have developed a piezoelectric nanogenerator (PNG) with zinc oxide (ZnO) nanoparticles and polyvinylidene fluoride (PVDF) to serve as the matrix for the coating structure. The power generated by the composite samples was enhanced to 4.2 V compared to 1.2 V for the samples of pure PVDF. The characteristics of these structures were assessed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrical properties of the film were measured using a Wavesurfer oscilloscope. This result can be used for various wearable devices, such as water strider robot systems and equipment that run on their own.
