Abstract Addressing the diverse environmental demands for electronic material performance, design of a multifunctional ionic conductive hydrogel with mechanical flexibility, anti‐freezing capability, and antibacterial characteristics represents an optimal solution. Leveraging Dead Sea effect strong hydrogen bonding, this study exploits CaCl 2 abundant hydroxyl groups in phytic acid (PA) to induce chain entanglements, thereby constructing complex, multi‐crosslinked network. Furthermore, PA ternary solvent systems (CaCl /Glycerol/H O) synergistically impart excellent strength, toughness (with tensile strength 8.93 MPa, elongation at break 859.93%, 39.92 MJ m −3 ), high electrical conductivity, antifreeze properties, strain sensitivity (gauge factor up 2.10) hydrogels. Remarkably, structure maintains stability even after undergoing 6000 loading‐unloading cycles, demonstrating its outstanding fatigue resistance. Upon receiving external stimuli, exhibits response time 126 ms, making it ideal dynamic monitoring human motion signals. This offers novel insight into potential application hydrogels as flexible sensors challenging environments.
