ABSTRACT The contradiction between the widespread application of basalt fibers (BFs) and their poor interfacial interaction with polymers has become an urgent issue for preparation BF/thermosetting polymer composites. In this study, zinc oxide (ZnO) nanofibers were successfully grown on surface BFs through a modification process involving polydopamine (PDA) coating, followed by two‐step hydrothermal method to create interlocking structure. As result, modified epoxy resin was significantly enhanced, as evidenced increase in shear strength from 13.3 22.4 MPa, greatly improving mechanical properties resulting composite. impact toughness flexural composites increased 46.4 kJ/m 2 278.4 MPa 59.6 347.5 respectively. This not only addresses weak expand potential BFs, but also provides effective strategy other inorganic enhance polymer.

Triboelectric textiles have recently garnered significant attention for their ability to detect and analyze body movements. However, the transmission of wireless signals from natural human motion via integrated triboelectric wearables has been hampered by reliance on nontextile components, physical interface spacers, wired connections. Here, we report a biosensing wearable system that exploits inherent microgaps within electrospun nanofibers create textile, seamlessly woven into garment at various positions. This design enables untethered continuous biosignal monitoring, including those indicative stride-time variability joint-time analysis daily activities exercise.

Abstract Flexible ionic conductors hold potential for wearable sensors and energy harvesting. However, most gel‐based suffer from solvent evaporation liquid leakage, limiting practical applications. Although solid‐state mitigate these issues, achieving strong mechanics, high conductivity, self‐healing, stability remains challenging. Here, by integrating supramolecular engineering dynamic covalent adaptive networks, a self‐healing polyurethane‐based ion‐conductive elastomer (DACPU/100Li) with outstanding overall properties is successfully synthesized. DACPU/100Li exhibits ultrahigh conductivity (1.23 × 10 − 3 S cm −1 ) tensile strength (7.62 MPa), along an elongation at break of 1200%. Additionally, it excellent tear resistance fracture 45.6 kJ m 2 , 96% efficiency (after 120 °C 24 h), good recyclability, under extreme conditions. The DACPU/100Li‐based sensor has sensitivity (5.89) wide strain range (0.1–1000%). Integrated machine learning, enables precise gesture recognition human–machine interaction.
