Application of Triboelectric Nanogenerators on Manipulators

The exacerbation of the energy crisis has led to the development of various self-powered sensors, resulting in rapid advancements in the energy field. The sensor based on the triboelectric nanogenerator (TENG) is particularly effective in collecting mechanical energy from low-frequency and irregular movement. It can convert external mechanical forces directly into electrical signals, making it a self-powered (or self-driven) sensor. High-performance TENGs are widely used in flexible sensing, implantable power supplies, healthcare, and biomedical applications. This paper introduces TENG power generation methods, advantages, and disadvantages of TENG, summarizes the related research of TENG simulation, material selection, sensor fabrication, etc., and reviews applied research of TENG in manipulators. Finally, the current challenges and problems facing TENG-based sensors are discussed, and the future development of TENG technology is explored.
