Integrating self\u2010healing functionality into triboelectric substrates is an effective approach to address these bottlenecks, but it remains challenging to simultaneously realize superior stretchability, steady electrical output, and efficient self\u2010healing performance in a single material system. Inspired by the arm structure of brittle stars, a waterborne polyurethane (WPU) incorporating dynamic disulfide and hydrogen bonds was fabricated, and the hydrogen\u2010bonding interfacial network between MXene and WPU was tailored. A composite system enabling synergistic multilevel energy dissipation through reversible dynamic bonds and disulfide exchange was therefore constructed. The resulting MXene\/WPU (M\u2010WPU) composite film exhibits a tensile strength of 14.7\u00a0MPa, an elongation at break of 970%, a triboelectric output of 14\u00a0\u00b5A, and a self\u2010healing efficiency of 89% after thermal healing at 100\u00b0C for 12\u00a0h. The flexible sensor assembled from this M\u2010WPU film, integrated with machine learning, enables accurate handwriting recognition and human\u2013machine interaction. Notably, after macroscopic crack self\u2010healing, the M\u2010WPU can still maintain stable electrical signal output, offering novel design insights for the development of long\u2010life, highly reliable self\u2010powered flexible sensors.<\/jats:p>","DOI":"10.1002\/smtd.71107","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T10:50:09Z","timestamp":1791543009000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Brittle
