Recently, hydrogel-based conductive materials and their applications as smart wearable devices have been paid tremendous attention due to high stretchability, flexibility, excellent biocompatibility. Compared with single functional hydrogels, multifunctional hydrogels are more advantageous match various demands for practical applications. This review focuses on applied devices. Representative strategies conduction of discussed firstly: (1) electronic based the fillers (2) ionic charged ions. Then, common intensive research multiple functionalities such mechanical properties, sensory anti-freezing moisturizing adhesion self-healing properties is presented. The in human motion sensors, skins, personal healthcare diagnosis provided third part. Finally, we offer our perspective open challenges future areas interest used

Abstract Inspired by shape‐morphing organisms in nature, researchers have developed various hydrogels with stimuli‐responsive swelling, shrinking, bending, folding, origami, rolling, twisting, or locomotion. These smart are usually created patterning 4D printing. The shape morphing of allows the fabrication helixing, and rolling microstructures, all which hard to reproduce directly ordinary techniques. More importantly, under external stimuli (e.g., solvent, humidity, temperature, light, pH, electric/magnetic fields), many exhibit recoverable thus find promising applications grippers, sensors, valves, soft robotics, etc. Since determines functions a great number cases, herein, recent advances summarized, their types, mechanisms, methods, modes, extensive covered. conclusion perspectives also presented guide design functional hydrogels.

Abstract The healing of diabetic wounds is hindered by various factors, including bacterial infection, macrophage dysfunction, excess proinflammatory cytokines, high levels reactive oxygen species, and sustained hypoxia. These factors collectively impede cellular behaviors the process. Consequently, this review presents intelligent hydrogels equipped with multifunctional capacities, which enable them to dynamically respond microenvironment accelerate wound in ways, stimuli ‐responsiveness, injectable self‐healing, shape ‐memory, conductive real‐time monitoring properties. relationship between multiple functions also discussed. Based on wounds, antibacterial, anti‐inflammatory, immunomodulatory, antioxidant, pro‐angiogenic strategies are combined hydrogels. application repair systematically discussed, aiming provide guidelines for fabricating exploring role therapeutic processes.

Abstract Flexible electronics are playing an increasingly important role in human health monitoring and healthcare diagnosis. Strong adhesion on tissue would be ideal for reducing interface resistance motion artifacts, but arising problems such as skin irritation, rubefaction, pain upon device removal have hampered their utility. Here, inspired by the temperature reversibility of hydrogen bonding, a skin-friendly conductive hydrogel with multiple-hydrogen bonds was designed using biocompatible poly(vinyl alcohol) (PVA), phytic acid (PA), gelatin (Gel). The obtained PVA/PA/Gel (PPG) temperature-triggered tunable mechanic could reliably adhere to detect electrophysiological signals under hot compress while readily removed cool compress. Furthermore, additional advantages transparency, breathability, antimicrobial activity PPG ensure its long-time wearable value skin. It is both environmentally friendly cost saving waste during production can recycled based reversible physical bonding. sensor expected good application prospects record monitoring.

Abstract The growing interest in mimicry of biological skins greatly promotes the birth high‐performance artificial skins. Chameleon can actively transform environmental information into bioelectrical and color‐change signals simultaneously through manipulating ion transduction photonic nanostructures. Here, inspired by chameleon skins, a novel biomimetic chromotropic photonic‐ionic skin (PI‐skin) capable outputting synergistic electrical optical under strain with robust adhesion, stability, resilience is ingeniously constructed. PI‐skin exhibits sensitive structural color change synchronized response via adjusting lattice spacing crystal (mechanochromic sensitivity: 1.89 nm per %, Δ λ > 150 nm). Notably, polyzwitterionic network provides abundant electrostatic interactions, endowing excellent tolerance, outstanding mechanical stability ( 10 000 continuous cycles). Meanwhile, high loading ionic liquid (IL) weakens interaction between molecular chains, leading to resilience. finally applied construct visually interactive wearable device, realizing precise human motion monitoring, remote communication, visual localization pressure distribution. This work not only expands design ideas for construction advanced I‐skins but also general platform high‐level devices smart electronics.
