Abstract Wearable healthcare and IoT applications demand conductors that are tough, stretchable, exhibit skin-like elasticity, advanced sensing capabilities, durability under dynamic conditions. However, conventional ionic conductors, such as hydrogels eutectogels, suffer from low conductivity, poor fatigue resistance, limited adaptability to deformation, constrained by trade-offs between mechanical robustness electrical performance. Here, we present an ultrastretchable, fatigue-resistant organic mixed ionic-electronic conductor (OMIEC) eutectogel addresses these challenges enhancing inherently competing properties through a novel hierarchical bonding network. This structure integrates hydrogen bonds within polymerizable deep eutectic solvent (PDES) matrix hydrophobic interactions derived rigid, mixed-conductive domains, forming robust conducting gel synergistic design significantly enhances toughness, fracture electromechanical sensitivity, while maintaining ultralow hysteresis (≤ 1%) strains up 1,500%. The OMIEC demonstrates 66-fold increase in 6.2-fold improvement energy, 4.5-fold enhancement complemented self-healing extend life beyond 100,000 cycles. By integrating the material eliminates traditional trade-offs, enabling precise stable monitoring of physiological motion, temperature, complex human gestures environments. multifunctional establishes transformative platform for next-generation wearable bioelectronics, providing unparalleled stretchability, durability, multi-sensing performance health monitoring, soft robotics, systems.
