In recent years, wearable technology designed for tracking human motion has garnered significant interest. this study, we developed a wire-structured triboelectric nanogenerator (W-TENG) incorporating polytetrafluoroethylene and nylon wires, both mechanical energy harvesting real-time monitoring of jumping motion. The rough-textured, wear-resistant layers enhance durability lifespan. Unlike thin-film counterparts, the wire-based structure adapts better to dynamic deformations, ensuring robustness efficiency. W-TENG achieved outstanding performance metrics, including an open-circuit voltage (VOC) 847 V, short-circuit current (ISC) 80 μA, transferred charge (QSC) 165 nC, with peak output power 4.56 mW at optimal load resistance ∼60 MΩ. With its high sensitivity precision, enables detailed posture during activities, effectively capturing lower-limb dynamics, such as take-off, mid-air motion, landing impact. tracks fluctuations from jump intensities, optimizing performance, assessing stability, preventing injuries. This versatile, sustainable sensor advances sensing in fitness, sports science, rehabilitation.

All-weather anti-icing/deicing materials with photothermal and electrothermal functionalities are of substantial significance to solve the problem ice accumulation. In this work, polypropylene bionic rose petal micro-/nanostructures conductive carbon black (CB) (Bionic PP/CB) is fabricated by a template method. The obtained replicating fresh petals phenolic resin spraying CB. contact angle Bionic PP/CB up 162.5°, rolling as low 2.5°. superhydrophobicity theoretically analyzed calculating liquid–air area surface energy. adhesion strength 6.06 kPa. Due incorporation CB, effects ultraviolet light, acid immersion, friction on superhydrophobic properties can be effectively mitigated. performance has been improved, it used for anti-icing. CB form paths achieve conversion, which compensate insufficient sunlight. temperature reach 132 °C at 15 V, greatly shorten melting time prevent frosting. Leveraging synergistic functionalities, combined promising applications in fabrication low-cost, energy-efficient, all-weather materials.
