Conductive hydrogels are ideal materials for intelligent medical devices, human-machine interfaces, and flexible bioelectrodes due to their adjustable mechanical properties electrical responsiveness, whereas it is still a great challenge achieve the integration of excellent flexibility biocompatibility into one hydrogel sensor while also incorporating self-healing, self-adhesion, environmental tolerance, antimicrobial properties. Here, nanocomposite conductive organohydrogel was constructed by using collagen (Col), alginate-derived carbon quantum dots (OSA-CQDs), poly(acrylic acid) (PAA), ethylene glycol reduced AgNPs, Fe3+ ions. Depending on OSA-CQDs with multiple chemical binding sites high specific surface area as cross-linkers, coupling highly biologically active Col chains PAA serving an energy dissipation module, resulting exhibited (795% strain, 193 kPa strength), cell compatibility (>95% survival rate), self-healing efficiency (HE = 79.5%), antifreezing (−20 °C), moisturizing (>120 h), repeatable adhesion (strength >20 kPa, times >10), inhibitory activity against Escherichia coli Staphylococcus aureus (9 21.5 cm2), conductivity, strain sensitivity (σ 1.34 S/m, gauge factor (GF) 11.63). Based all-in-one multifunction, can collaboratively adapt multimode sensing electrophysiological realize wireless real-time monitoring human activities physiological health. Therefore, this work provides new common platform design next-generation hydrogel-based smart wearable sensors.

Abstract Multi‐functional hydrogels have gained attention for their potential as smart materials in diverse applications. However, most established design principles and fabrication methods are considered convoluted ineffective. Here, by using a simple one‐pot efficient method, novel PAAm/Gelatin/Ammonium sulfate organohydrogel (PGAOH) with exceptional multifunctionality, including anti‐freezing properties, excellent conductivity, remarkable stability, free‐shapeable, sensitivity, elasticity, high transparency, resistance to drying is developed. In this system, it surprisingly discovered that the presence of acrylamide molecules, gelatin can disperse well high‐concentration salting‐out solutions, significantly shorten preparation time gel, allows precise control gel volume. More importantly, form another polyacrylamide network, further enhancing mechanical properties PGAOH. Additionally, introduction glycerol notably improved environmental stability PGAOH effectively enhanced its transparency. These innovative combinations result possessing demonstrated successful application wireless virtual reality (VR) gaming device.

Abstract Ionic conductive hydrogels (ICHs) are emerging as key materials for advanced human‐machine interactions and health monitoring systems due to their unique combination of flexibility, biocompatibility, electrical conductivity. However, a major challenge remains in developing ICHs that simultaneously exhibit high ionic conductivity, self‐healing, strong adhesion, particularly under extreme low‐temperature conditions. In this study, novel ICH composed sulfobetaine methacrylate, methacrylic acid, TEMPO‐oxidized cellulose nanofibers, sodium alginate, lithium chloride is presented. The hydrogel designed with hydrogen‐bonded chemically crosslinked network, achieving excellent conductivity (0.49 ± 0.05 S m −1 ), adhesion (36.73 2.28 kPa), self‐healing capacity even at −80 °C. Furthermore, the maintain functionality over 45 days, showcasing outstanding anti‐freezing properties. This material demonstrates significant potential non‐invasive, continuous monitoring, adhering conformally skin without signal crosstalk, enabling real‐time, high‐fidelity transmission cryogenic These offer transformative next generation multimodal sensors, broadening application possibilities harsh environments, including weather outer space.
