Abstract The cracks in flexible triboelectric nanogenerators (TENG) cannot naturally repair themselves during low‐temperature operation, which significantly restricts their practical applications. Yet, the development of elastomers capable self‐repair at low temperatures has remained a formidable challenge. In this study, dual dynamic cross‐linking network using multiple hydrogen bonds and β ‐hydroxy esters is constructed to fabricate fully bio‐based elastomer known as PLMBE. This can be stretched up an impressive 1200% its original length possesses remarkable autonomous self‐healing capability even under harsh conditions, including (−10 °C, 12 h, with 75% efficiency rate) exposure supercooled, high‐concentration saline (10% NaCl solution −10 64% rate). These properties are attributed elastomer's glass transition temperature (Tg) −30 °C abundance hydrogen‐bonded supramolecular interactions. Importantly, highly suitable layer for creating TENG (Bio‐TENG) . results demonstrate that Bio‐TENG achieve output power density 2.4 W m −2 , voltage recovers 95% after °C. Consequently, these have promising applications various fields, energy storage devices.
