Abstract Non‐contact human‐machine interaction is the future trend for wearable technologies. This demand recently highlighted by pandemic of coronavirus disease (COVID‐19). Herein, an anti‐fatigue and highly conductive hydrogel thermocell with photo‐thermal conversion ability non‐contact self‐powering applications designed. Double hydrogen‐bonding enhanced supramolecular obtained N‐acryloyl glycinamide (NAGA) diacrylate capped Pluronic F68 (F68‐DA) via one‐step photo‐initiated polymerization. The can accommodate saturated electrolytes to fulfill triple function ionic crosslinking, heat‐to‐electricity conversion, light response thermocell. Eminently, stands out virtue its high seebeck coefficient (‐2.17 mV K −1 ) extraordinary toughness (Fatigue threshold ≈ 3120 J m −2 ). under control heating explored, a model “light‐remoted” sensor self‐powered sensing integrated performance remote‐controlled constructed. It believed that this study will pave way energy supply devices.
