Abstract Ionic conductive hydrogels (ICHs) are emerging as key materials for advanced human‐machine interactions and health monitoring systems due to their unique combination of flexibility, biocompatibility, electrical conductivity. However, a major challenge remains in developing ICHs that simultaneously exhibit high ionic conductivity, self‐healing, strong adhesion, particularly under extreme low‐temperature conditions. In this study, novel ICH composed sulfobetaine methacrylate, methacrylic acid, TEMPO‐oxidized cellulose nanofibers, sodium alginate, lithium chloride is presented. The hydrogel designed with hydrogen‐bonded chemically crosslinked network, achieving excellent conductivity (0.49 ± 0.05 S m −1 ), adhesion (36.73 2.28 kPa), self‐healing capacity even at −80 °C. Furthermore, the maintain functionality over 45 days, showcasing outstanding anti‐freezing properties. This material demonstrates significant potential non‐invasive, continuous monitoring, adhering conformally skin without signal crosstalk, enabling real‐time, high‐fidelity transmission cryogenic These offer transformative next generation multimodal sensors, broadening application possibilities harsh environments, including weather outer space.
