Abstract Conductive hydrogels have emerged as fascinating materials for flexible electronics because of their integrated conductivity, mechanical flexibility, and the possibility to introduce several smart functions. However, swelling in aqueous environments significantly reduces applicability where contact with water is unavoidable. In this study, a physically cross‐linked composite hydrogel proposed, that transparent, highly stretchable, anti‐swelling, capable autonomous self‐healing, adhesive, anti‐freezing. The synthesized through simple one‐step photopolymerization novel deep eutectic solvent (DES)/water system. Dynamic physical interactions, including hydrophobic interaction, hydrogen bonding, electrostatic confer remarkable transparency (92%), self‐healing capability (up 94%), good adhesion wide array substrates (91 199 kPa), high toughness (1.46 MJ m −3 ), excellent elongation at break 2064%), resistance (equilibrium ratio 3% 30 days) even solutions different pH (pH 1–11), other solvents. incorporation DES contributes exceptional anti‐freezing performance. transparent sensor achieves multifunctional sensing human motion detection sensitivity stability. Notably, demonstrates information transmission underwater stretching pressing, showcasing its immense potential devices.

Bioelectronics based on regular hydrogels containing conductive components severely suffer from inferior structural compatibility, impaired signal accuracy, and fatigue failure under harsh environments, thus constraining their multifunctionalities. To address the issues of additive agglomeration phase separation within polymer matrix, assembly amphiphilic nanosheets at oil/water interfaces for costabilization is innovatively proposed. The critically dispersed graphene nanosheets, assisted by ionic liquid (IL) graft-exfoliation, can be chemically integrated into swelling-resistant polymeric networks through ultrasonic-induced gelation. Additionally, synergistic effect between dimethyl sulfoxide (DMSO)/H2O binary solvents charged polar terminal groups weakens hydrogen bonding water molecules, enabling organohydrogel with reliable environmental tolerance long-lasting moisture retention. Owing to its high mechanical stretchability, satisfactory sensitivity, exceptional photothermal conversion behavior, fast prepared fabricated an all-climate wearable sensor daily activities detection temperature sensing, which lays groundwork human–machine interaction thermosensation-based actuation.
