Abstract Hydrogels emerge as highly promising candidates for wearable electronics due to their moldability and biocompatibility. However, hydrogel‐based often suffer from poor mechanical properties limited adhesion, pose significant challenges practical application. Herein, a conductive, stretchable, self‐adhesive gelatin/slide ring hydrogel (SRH) with double‐network (DN) structure is developed by incorporating polyrotaxane (PR) based cross‐linker in the gelatin (GEL) network. The water‐soluble allylic PR (APR) cross‐linkers are prepared cyclodextrin‐based via simple one‐step method. Additionally, effect of APR different sliding capabilities on SRH further investigated aiming optimize performance. optimized achieves balance between toughness (2226 kJ m −3 ) rigidity (154 kPa), along high stretchability (3048%) strong adhesion various substrate materials. More importantly, this DN demonstrated human motion sensor capable Morse code communication. This work not only advances understanding slidable applications but also paves way innovative hydrogels tailored high‐performance electronics, broadening scope functionality real‐world use.
