FABRICATION OF PORTABLE TRIBOELECTRIC NANOGENERATOR BASED ON NATURAL LEAVES

Abstract

Recently, green triboelectric nanogenerators (TENG) have emerged as an alternative adequate power supply to solid-state chemical batteries to overcome certain drawbacks, including toxic materials, limited lifetime, or recharged requirement. In this paper, we demonstrated the fabrication of the natural and common leaf-based triboelectric nanogenerator (NF-TENG), which uses jackfruit, banana, and bamboo leaves as positive triboelectric layers. Among some fabricated NF-TENGs, the bamboo leaf-based TENG presents novel output characteristics, including the maximum output power density of 7 mW.m⁻², the short-circuit current of 6 μA under the excitation power and the frequency supplied to the mechanical oscillator of 33.6 mW and 30 Hz. This NF-TENG can light up 18 green commercial LEDs simultaneously, which promises to be a novel solution for powering low-power electronic devices using different vibration energy sources.
