Considering that solar energy is dependent on the weather and people stay most of a day indoors, mechanical energy could be an appropriate complement due to its universal availability. The triboelectric nanogenerator (TENG),[13, 14] coupling the effect of contact-electrification and electrostatic induction, has been demonstrated to be versatile in scavenging different types of mechanical energies, ranging from vibration,[15] wind,[16] water wave,[17] to human motions.[18–20] The abundant choice of materials and structure designs of the TENG enable its feasibility in integration with the E-textile for harvesting energy from human motions. Silver coating,[21] carbon nanotubes,[22] and carbon fiber [23] were applied to textile fibers, functioning as the electrode of the textile-based or fiber-based TENG. In our previous studies, a woven TENG textile was realized by electroless deposition (ELD) of conformal and low-cost nickel coating to convert textile yarns/fabrics into conductive electrodes.[24] Despite these preliminary findings, further research is still required to improve the output power of the TENG textile. Meanwhile, integration of the whole textile-based TENG and solar cell has seldom been found in literature, though several previous works have been reported integrated devices on flat substrates.[25]

Herein, we developed a grating-structured TENG fabric and its integration with FDSSCs so as to achieve a whole textile-based energy harvesting system. A route of laser-scribing masking and ELD Ni plating was first proposed for the synthesis of conductive circuits/patterns on the textile. Interdigitated grating-structured TENG fabrics were then …
