Soft self-healing materials are excellent candidates for wearable devices to power sensors due to their excellent compliance, extensibility, and self-restorability. However, combining ultrafast and autonomous restorative properties with excellent mechanical capabilities for application in self-powered wearable device still poses challenges. Utilizing the high mobility and conductivity of liquid metal, this paper incorporates it into polydimethylsiloxane by a supra-molecular interfacial assembly strategy to prepare a triboelectric material with ultrahigh stretchability (12000%) and remarkable self-healing (30 min at ~25 °C). The dynamic bonds endow the material with excellent and universal self-healing ability under extreme environments (?20 °C, near infrared, and underwater), mechanical durability, and triboelectric properties (100 V and 0.81 W/m2). By integrating the material into wearable self-powered devices, real-time feedback on human joint movement is enabled. This work offers a valuable strategy to balance the trade-off between shape adaptation and self-healing, paving the way for enhanced applicability in sensing applications.
