Abstract

Single-electrode triboelectric nanogenerator (TENG) exhibits significant potential applications in harvesting kinetic energy from human body movements due to its simple and flexible structure. In this work, we report a facile and low-cost external single-electrode sole triboelectric nanogenerator (TENG) for harvesting human motion energy dissipated in the environment. The sole TENG is assembled only by attaching the PTFE film to the sole. Different test scenarios are characterized to demonstrate the feasibility of the TENG. The characterization results of sole TENG exhibit excellent performance, especially the sole TENG under wood plate scenarios could obtain an output open-circuit voltage of 100 V, a short-circuit current of 6.5 µA, and an instantaneous power of 61 μW under external resistance of 20 MΩ. The excellent output of sole TENG could provide a sustainable power supply to directly drive more than 60 LEDs and power a calculator via a capacitor. The facile and low-cost assembling process and output characteristics indicate that the sole TENG has the potential for practical application.
