Energy harvesting textiles (EHTs) have attracted much attention in wearable electronics and the intet-of-things for real-time mechanical energy harvest-ing associated with human activities. However, to satisfy practical application requirements, especially the demand for long-term use, it is challenging to construct an energy harvesting textile with elegant trade-off between mechani-cal and triboelectric performance. In this study, an energy harvesting textile was constructed using natural silk inspired hierarchical structural designs combined with rational mate-rial screening; this design strategy provides multiscale opportunities to optimize the mechanical and triboelectric performance of the final textile system. The resulting EHTs with traditional advantages of textiles showed good mechani-cal properties (tensile strength of 237?±?13 MPa and tough-ness of 4.5?±?0.4 MJ m?3 for single ys), high power output (3.5?mW -m?2), and excellent structural stability (99% conductivity maintained after 2.3 million multi-type cyclic deformations without severe change in appearance), exhibiting broad application prospects in integrated intelligent clothing, energy harvesting, and human-interactive interfaces.
