Abstract Traditional hydrogels tend to freeze and lose performance at low temperatures, limiting their applications. Additionally, need exhibit hysteresis, excellent cycling stability, self‐adhesion ensure high‐quality signal acquisition in complex environments. To address this challenge, study designed a dual‐network gel glycerol (Gly)/H 2 O solvent system. Due the combination of chemical physical crosslinking (hydrogen bonding electrostatic interactions), resulting exhibits skin‐adaptive modulus, high anti‐freezing ability, body temperature‐induced adhesion, electrical performance, making it suitable for wearable sensors temperatures. Based on gel, single‐electrode triboelectric nanogenerator (gel‐TENG) is developed, achieving efficient conversion mechanical energy into energy. Further applied smart insole, successfully enabled real‐time visualization plantar pressure distribution skiing motion recognition. Using random forest machine learning algorithm, system accurately classified 11 basic motions, classification accuracy 97.1%. This advances flexible self‐powered systems, supporting intelligent materials research extreme
