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.
