Abstract:
Textile-based triboelectric nanogenerators (T-TENGs) show great potential in the field of energy harvesting and wearable devices, especially in sports and health fields. This paper reviews the recent advances of textile-based friction nanogenerators in the field of motion and health. Firstly, the principle and mode of Triboelectric nanogenerator (TENG) are introduced. As well as the key materials of T-TENGs are summarized, including electrodes and positive and negative triboelectric materials. Secondly, various preparation techniques, such as conjugate electrostatic spinning, wet spinning, ring spinning, 2D braided technology, 3D braided technology, and electrostatic spinning film. The manufactures of T-TENGs in different structures such as knitted, woven, non-woven, embroidered and 3D printed fabrics are discussed. Recent applications of T-TENGs in motion fields (human movement monitoring and applications in different sports) and health fields including vital signs monitoring, health monitoring, disease monitoring, prevention and treatment are introduced subsequently. Finally, a discussion of the challenges, the future trends of T-TENGs and the promise of its extensive use in multifunctional field. It aims to provide reference for further research and preparation of textile-based triboelectric nanogenerators.
