Hydrogels are widely applied in the flexible wearable electronic devices field owing to their skin-like stretchability, superb biocompatibility, and high conductivity retention under mechanical deformations. Nevertheless, hydrogels prone freezing at low temperatures losing water temperatures, which seriously limits practical applications. Herein, a binary solvent system of ionic liquid (1-ethyl-3-methylimidazolium chloride) was prepared endow hydrogel (0.28 S m–1 25 °C), transparency (94.26%), superior tolerance (−50 °C). The multiple hydrogen bonds formed among polymer chains, water, liquids significantly improved properties hydrogel, enabling excellent tensile (strain >1800%) durability (1000 times 100% strain). Moreover, further assembled into dual-response sensor, exhibited satisfactory sensitivity both tension (gauge factor = 2.15 200% strain) temperature (temperature coefficient resistance −1.845%/°C) can be for human motion body monitoring. This study provides versatile method preparing multifunctional with wide range applications lays groundwork movement detection smart health care.
