Abstract
Among various emerging energy technologies, triboelectric nanogenerators (TENGs) have garnered significant attention due to their ability to convert environmental mechanical energy into electrical energy through triboelectric effect and electrostatic induction. The energy converted by TENGs can power microelectronic devices. This paper proposes a high-performance TENG enhanced with BaTiO₃nanowires(BTONWs). Using electrospinning technology, BTONWs were mixed with PVDF to fabricate a TENG with high flexibility and efficient energy conversion in a porous structure. BaTiO₃ and PVDF all exhibited piezoelectric and triboelectric properties, maximizing the conversion of pressure into electrical energy output. This integration effectively enhanced conversion power and provides continuous energy supply. Experimental results show that the fabricated TENG achieved a current and voltage of 11 µA and 175 V, respectively, with a maximum power density of 0.648 mW at a load resistance of 90 MΩ. Additionally, the performance of the TENG was tested using a calculator, a timer, and LED lights. By connecting to a simple external circuit and continuously tapping the TENG, the devices functioned normally, demonstrating that the TENG can continuously and stably output electrical energy by continuously collecting mechanical energy to power micro-generators. This makes a significant contribution to the development of energy harvesting, wearable devices, and micro-power sources.
