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.

Slide-ring polymers exhibit distinctive mechanical properties, making them highly promising for applications in emerging fields such as energy storage devices and smart sensing. However, existing slide-ring polymer systems primarily rely on hydrophilic-hydrophobic interactions to achieve ring-axle interlocking aqueous phases. This reliance limits the construction of networks mainly water-soluble polymers, excluding a diverse range lipophilic polymers. Therefore, it is crucial introduce efficient strategies that facilitate interpenetration organic solvents, enabling development expanding their applications. Herein, by utilizing pillar[5]arene/alkyl chain host-guest interactions, we successfully facilitated pillar[5]arene poly(caprolactone), two solvents.
