Lead-free piezoelectric nano-based generator with energy harvesting has drawn a great attention in the recent years. BaTiO3 as a lead-free material with high piezoelectric coefficient and dielectric constant has been widely examined to realize nanogenerators. In this work, high-quality BaTiO3 (BTO) nanowires were prepared by hydrothermal synthesis as the piezoelectric material and then BTO/PVDF-based nanogenerators have been fabricated. Furthermore, the CNTs were added to improve the output voltage performance of the nanogenerator. It shows high performance of a maximum output voltage density of 7.3 V/cm(2) and the stable current density of 3.3 nA/cm(2). This hybrid nanogenerator with enhanced performance is a potential material for the application in harvesting energy, self-powered electronics and low-frequency capacitors.
