Multilayered and Multifunctional Triboelectric Nanogenerator
摘要
This work reports a multifunctional, multilayered zigzag-shaped triboelectric nanogenerator (TENG) array developed as a potential candidate for low-cost biomechanical sensing applications. The device was fabricated from alternating Cu and polytetrafluoroethylene (PTFE) layers using straightforward assembly process. A three-unit TENG configuration shows power output of 26.67 µW, while a six-unit TENG shows maximum power output of 70.8645 µW under a 10 MΩ matched load. The feasibility of the device is explored as a conceptual smart floor mat counter to track indoor occupancy by monitoring individuals entering and exiting specific areas. Additionally, experimental studies on tracking knee and arm movements suggest its possible utility in physiotherapy, fall detection, and sports biomechanics. While this study focuses primarily on real-time sensing responses, it may offer a baseline framework for future energy-harvesting integration via circuit and charge-storage optimization.
