Abstract The escalating threats posed by global warming highlight the need to develop multi‐functional wearable materials that integrate personal thermal management and sustainable energy technologies. Despite progress in radiative cooling textiles, integrating inorganic nanoarchitectonics and biological matrices while maintaining human‐centric functionalities remains a major challenge. This study presents a bio‐inspired interface engineering strategy to construct biomimetic wearable materials through dynamical molecular‐level welding of halloysite nanotubes with natural skin‐derived frameworks. The resultant hierarchical skin prosthesis (HSP‐skin) features multi‐dimensional interfacial crosslinking networks that enable unprecedented optical‐thermal regulation (93.4% solar reflectance and 94.2% mid‐infrared emissivity) and triboelectric polarization enhancement. Demonstrating a net radiative cooling power of 88.7 W m − 2 under peak solar irradiation, HSP‐skin achieves sub‐ambient temperature drops of above 10.29 °C while generating significant triboelectric outputs (8.68 W m − 2 power density) through biomechanical energy harvesting. Moreover, the biomimetic architecture confers intelligent wearability, showing outstanding moisture‐vapor permeability, anisotropic thermal insulation (0.059 W·m −1 ·K −1 ), and flame‐retardant self‐extinguishing properties. The continuous radiative cooling endurance and physiological signal monitoring capabilities have been verified in field tri...
