TENG-based self-powered device- the heart of life.

As an energy source for the new era and an excellent candidate for building self-powered energy equipment, triboelectric nanogenerators can absorb various forms of energy existing in the environment through transducer elements, realizing self-drive away from traditional energy sources. With simple structure, inexpensive, small size, strong biocompatibility and high instantaneous power density, it has become an attractive supporting technology in the field of Internet of Things. Triboelectric nanogenerator not only provides continuous energy for a variety of devices, but also reflect the health of the organism in real time when coupled to specific biochemical or physiological reactions. Considerable research has demonstrated that the design of TENG-based self-powered plants is an extremely promising strategy, especially in the field of life and health. With the rapid development of wearable and implantable devices, TENG can lay the foundation for these healthcare preparations from the low-frequency mechanical energy in the body. When it is attached to the surface or inside the body, like the heart, it provides a constant source of power for the operation of life in the continuous process of contact and separation. This review briefly introduces the basic working principle and mode of TENG, the latest application and research progress on the performance improvement of TENG-based self-powered equipment. The conclusion of is that TENG-based self-powered energy devices are an important development direction in the field of life and health in the future, laying the foundation for real-time and continuous in situ monitoring and treatment.
