Abstract Hydrogels have received great attention due to their molecular designability and wide application range. However, they are prone freeze at low temperatures the existence of mass water molecules, which can damage flexibility transparency, greatly limiting use in cold environments. Although adding cryoprotectants reduce freezing point hydrogels, it may also deteriorate mechanical properties face risk cryoprotectant leakage. Herein, microphase‐separated structures hydrogels regulated confine molecules sub‐6 nm nanochannels increase proportion bound water, endowing with intrinsic anti‐freezing properties, high strength, good stretchability, remarkable fracture energy, puncture resistance. Even after being kept liquid nitrogen for 1000 h, hydrogel still maintains transparency. The exhibit excellent low‐temperature shape memory intelligent optical waveguide properties. Additionally, be assembled into strain pressure sensors flexible sensing both room temperatures. intrinsically offers broad prospects electronic applications.
