Textile-based triboelectric nanogenerator with alternating positive and negative freestanding woven structure for harvesting sliding energy in all directions

A novel textile-based triboelectric nanogenerator (TENG) with woven structure operating in freestanding triboelectric-layer mode, defined as a woven-TENG, has been developed. Whereas most woven-structured TENGs operate contact-separation mode and consist of one type material, this woven-TENG comprises electrodes strips positive negative which form checker-like pattern over the matching periodicity. The implementation material significantly improves performance woven-TENG. Furthermore, contrast to conventional grating-structured TENG, are designed only moving direction, new design also allows harvest energy from all-planar directions movement. nylon polytetrafluoroethylenevinyl (PTFE) fabric can generate root mean square (RMS) open-circuit voltage 62.9 V, an RMS short-circuit current 1.77 µA maximum power 34.8 µW at load resistance 50 M?, mechanical oscillation 2 Hz contact force 5 N. This corresponds density 5.43 mW/m2.
