Deep eutectic solvent (DES)-based eutectogels show significant promise for flexible sensors due to their high ionic conductivity, non-volatility, biocompatibility, and cost-effectiveness. However, achieving tough stretchable is challenging, as the highly polar DES tends screen noncovalent bonds, such hydrogen between polymer chains, limiting mechanical strength. In this work, issue addressed by leveraging limited solubility of zwitterionic polymers in a specific induce phase separation, promoting dipole-dipole interactions chains. These improve energy dissipation under stress, allowing creation P(MAA-co-VIPS)/TBAC-EG through copolymerization-induced separation approach. Methacrylic acid (MAA) sulfobetaine vinylimidazole (VIPS) are copolymerized within tetrabutylammonium chloride-ethylene glycol (TBAC-EG) DES, resulting bicontinuous network. The structure consists PVIPS-rich that enhances toughness via interactions, PMAA solvent-rich enables stretchability. eutectogel demonstrates excellent properties, including strength 1.76 MPa, 16.61 MJ m⁻
