Abstract In recent years, significant progress has been made in the research and development of conventional hydrogel sensors. However, hydrogels with special structures, achieved through specific designs or fabrication strategies, remains relatively scarce. Inspired by aloe, a specially structured (named Skin‐Polyvinyl alcohol‐Polyaniline‐AgNWs, S‐PPA) is successfully prepared skin. Innovatively utilizing hydrogen bonding interaction between ions water molecules, surface treated to create protective The S‐PPA skin demonstrates strong resistance damage (with tensile strength 5 MPa, >11 times higher compared without skin) exhibits dual conductivity (0.8 S m −1 for inner 0.33 outer skin). addition, also possesses retention capabilities, antibacterial properties (89.4% inhibition rate against Staphylococcus aureus ( S. )), minimal corrosion metal electrodes. Based on combined wireless Bluetooth technology Python programming, intelligent applications are developed such as multi‐gradient control finger muscle condition evaluation, achieving real‐time human‐ computer (HCI). pressure‐sensitive proposed this study shows great potential fields medical rehabilitation, artificial intelligence, Internet Things.

Abstract Conductive hydrogels have emerged as ideal candidate materials for strain sensors due to their signal transduction capability and tissue‐like flexibility, resembling human tissues. However, the presence of water molecules, can experience dehydration low‐temperature freezing, which greatly limits application scope sensors. In this study, an ionic co‐hybrid hydrogel called PBLL is proposed, utilizes amphoteric ion betaine hydrochloride (BH) in conjunction with hydrated lithium chloride (LiCl) thereby achieving function humidity adaptive. retains at low (<50%) absorbs from air high (>50%) over 17 days testing. Remarkably, also exhibits strong anti‐freezing properties (−80 °C), conductivity (8.18 S m −1 room temperature, 1.9 −80 gauge factor (GF approaching 5.1). Additionally, exhibit inhibitory effects against Escherichia coli (E. coli) Staphylococcus aureus (S. aureus), well biocompatibility. By synergistically integrating wireless transmission Internet Things (IoT) technologies, study has accomplished real‐time human‐computer interaction systems sports training rehabilitation evaluation. significant potential fields medical rehabilitation, artificial intelligence (AI), (IoT).

High-performance flexible strain sensors have tremendous potential applications in wearable devices and health monitoring. However, developing a sensor with high sensitivity over wide range remains significant challenge. In this study, fibrous membrane porous crimped structure was designed as the substrate material for TPU/GNPs sensors. This structural design effectively balances range. The TPU-PEO prepared using electrospinning water washing, resulted TPU framework. Subsequently, subjected to anhydrous ethanol stimulation obtain network structure. GNPs were modified on through ultrasonic treatment. produced exhibited (GF = 4047.5) within large (350%) demonstrated excellent sensing performance, stability, durability (>10,000 cycles). It not only captured basic movements but also efficiently recognized measured bending angles, enabling more sophisticated human–machine interaction experience. advancement opens up possibilities future intelligent technology interaction, contributing evolution of these fields.

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.
