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.

Hydrogels have attracted increasing attention in wearable sensors, but preparing underwater hydrogel sensors with excellent anti-swelling and self-healing properties is still challenging. Herein, an prepared by grafting poly(acrylic acid) hydrophobic lauryl methacrylate, as well constructing a second network multiple molecular interactions (abbreviated PALCF). The introduced long alkyl chains the increased cross-linking density of result swelling ratio only 0.04% after immersion water for 15 days. Due to abundant metal coordination hydrogen bonds, PALCF exhibits high tensile stress 0.60 MPa efficiency reaching 96.0% at 60 °C 2 min. Based on piezoresistive effect, directly used strain sensor sensitivity (GF = 2.24) control vehicles rescue implementation. Furthermore, two self-powered triboelectric nanogenerator contact non-contact models are constructed based hydrogels communication, capable sending out SOS messages drowning alarms emergency. proposed warning rescuing functions potential use prevention, human-machine interfaces, communication system.

Abstract Conductive hydrogels are a class of multifunctional composites constructed by introducing conductive components into three‐dimensional polymer network, combining the high water‐content, stretchability, and biocompatibility traditional hydrogels. In recent years, researchers have developed stimuli‐responsive (SRCHs) through molecular functionalization design, which can respond to external stimuli such as mechanical stress, temperature, pH, light, electric field, etc., realize electrical signal output or behavior modulation, so satisfy requirements smart devices for dynamic sensing active response materials. Thanks synergistic effect environmental responsiveness conductivity, SRCHs show broad application prospect in actuation. However, due complexity environment, it is still difficult utilize materials construct sophisticated devices. This paper systematically reviews progress material design actuation applications past five focuses on their mechanisms performance optimization strategies, summarizes current challenges future development directions, with view providing theoretical references technological inspirations next‐generation
