Summary: This study presents a self-healing triboelectric nanogenerator (TENG) fabricated using self-healing polyimide (PI) for energy harvesting and motion sensing. The PI-based TENGs exhibited excellent intrinsic self-healing properties, attributed to dynamic disulfide bond exchange and flexible PDMS fragments in the PI backbone. The output performance of the TENG was significantly improved due to CF3 electron-absorbing groups and siloxane fragments in the PI backbone. Practical applications of self-healing PI-based TENGs, including energy harvesting for commercial electronic devices and joint motion sensing, were demonstrated.
