Abstract
Today’s world is surrounded by smart wireless devices that require a sustainable and eco-friendly power source. PENGs (Piezoelectric nanogenerators) is fast emerging as an extremely efficient, cost-effective, and easily fabricated source for producing battery-free devices. This study involves using nanomaterials as an essential component in manufacturing such a self-powered system. Nanocomposites of P(VDF)/BaTiO3 containing varying amounts of nanoparticles were fabricated by far-field electrospinning. The non-woven composites were characterized with the field emission scanning electron microscope (FESEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). In this paper, we report an approach that allows us to fabricate a PENG based on piezoelectric polymer and nanofiller material nanocomposite as an active layer that can capture energy from daily life human activity (pressing and bending). P(VDF)/BaTiO3 nanogenerators exhibited higher piezoelectric performance than the pristine P(VDF) PENG. These PENGs could be able to produce enough energy to run LED bulbs. The results of this study provide a basis for developing self-powered electrical wearable devices and systems.
