Abstract Ionic conductive hydrogels have emerged as an excellent option for constructing dielectric layers of interfacial iontronic sensors. Among these, gradient ionic hydrogels, due to the intrinsic elastic modulus, can achieve a wide range pressure responses. However, fabrication with optimal mechanical and sensing properties remains challenge. In this study, it is discovered first that phytic acid (PA) interacts in remarkably distinct manners (i.e., plasticizing effects phase separation) different polymers polyacrylamide polyacrylic acid). This distinctive PA‐polymer interacting mechanism innovatively utilized construct modulus hydrogel through simple precursor solution infiltration approach. The hydrogel‐based flexible sensor not only achieves high sensitivity (9.00 kPa −1 , <15 kPa) broad (from ≈3.7 Pa 1.2 MPa) simultaneously, but also exhibits superior low performance. It successfully recognizes subtle acoustic waves airflow, well moderate speaking finger pressing magnitude plantar pressure. addition, demonstrates remarkable antibacterial biocompatibility. functional performance bioactivity exceptional potential wearable applications.

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.
