A Honeycomb‐Structured Triboelectric Nanogenerator Based on Polyester Cloth for Smart Running Application

Self-powered devices for human motion monitoring and energy harvesting have garnered widespread attention in recent research. In this work, we designed a honeycomb-structured triboelectric nanogenerator (H-TENG) using polyester cloth and Teflon tape, with aluminum foil as the conductive electrode. This design leverages the large surface area and flexibility of textiles, resulting in significant performance improvements. The H-TENG achieves an output voltage of 350 V, an output current of 42 μA, and a transfer charge (Q_SC) of 77 nC, with a maximum output power of 465 μW. Additionally, the H-TENG demonstrates the ability to monitor running activities and various gait patterns, providing real-time bio-mechanical data for smart running applications. The introduction of a stacked structure further enhances the output performance by increasing contact area and scalability, making the H-TENG a robust and high-performance energy harvester suitable for advanced wearable and flexible electronics.
