Abstract Eutectogels are emerging as the next‐generation stretchable electronics due to their superior ionic conductivity, non‐volatility, and cost‐effectiveness. Nevertheless, most eutectogels suffer from weak mechanical strength toughness pronounced hygroscopicity. Herein, a strategy is proposed fabricate phase‐separated with dual channels (PSDIC‐gel), which exhibit exceptional integrative properties, especially water resistance. By blending hydrophilic/hydrophobic polymerizable deep eutectic solvents, spontaneously form via polymerization‐induced phase separation. The hydrophilic poly(acrylic acid) (PAA) containing Li + ‐channels, rich in hydrogen bonding ion‐dipole interactions, provides conductivity. hydrophobic poly(hexafluorobutyl acrylate) (PHFBA) incorporating cholinium cation (Ch ) enhances toughness, Adjusting ratio yields microphase‐separated transparent eutectogel high tensile (6.03 MPa), (16.18 MJ m −3 ), excellent conductivity (1.6 × 10 S −1 strong substrate adhesion, rapid room‐temperature self‐healing. Solid‐state NMR reveals conductive mechanism structure featuring PSDIC‐gels, advancing understanding of complex interactions at atomic level. PSDIC‐gel enables flexible triboelectric nanogenerator for accurate real‐time self‐powered human motion sensing. This work advances design through structure‐property engineering, offering universal reconcile robustness, environmental suitability, wearable electronics.
