Physical activity is essential for physical health and mental well-being, while improper movements can cause serious injuries. To address this challenge, we developed a sweat-resistant, breathable, and antibacterial triboelectric sensor (BATS) for instantaneously monitoring of physical movements and reducing injury risks. The BATS was created using a hydrogen-bonded organic framework (HOF-101-F) embedded within polyvinylidene fluoride (PVDF) nanofibers. The resultant BATS system, when coupled with a logic circuit, will issue immediate warnings for improper movements or gestures, aiding in injury prevention. The BATS also present an excellent antibacterial property. The photoactive HOF-101-F generates singlet oxygen ( 1 O 2 ), achieving over 90% antibacterial efficacy against E. coli and inhibiting microbial growth under sweaty conditions during physical activity. Additionally, the incorporation of HOF-101-F enhanced the electrical output of the BATS by 250% compared to pure PVDF. Entirely fiber-based and air-permeable, the BATS can be integrated into sportswear. With its superior comfort, antibacterial efficacy, and exceptional sensitivity, the BATS hold significant promise for personalized health management.

Textured piezoelectric composites (PCs) based on dielectrophoresis (DEP) reveal great merits in both improving sensitivity and maintaining flexibility, thus trending to be promising candidates for high sensitive flexible sensors. However, the DEP technique shows poor applicability in fabricating textured PCs with high filling content, which severely limits further improvement of piezoelectric performance. Herein, we propose a new strategy to enhance DEP force by decorating Cu nanoparticles on Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 (BCZT) particles, thus textured BCZT@Cu/PDMS PCs with high filling content are obtained. The results proved that the enhanced DEP force is contributed by the excellent conductivity and capability of distorted electric fields of decorated Cu nanoparticles . Consequently, an ultrahigh piezoelectric voltage constant ( g 33 ) of 720 × 10 −3 Vm/N was achieved, which is much larger than that in other counterparts. Furthermore, the as-prepared piezoelectric sensor exhibits excellent sensitivity and flexibility, which can fit vulnerable joints like a band-aid seamlessly. On this basis, a flexible sport health monitoring system was developed, which shows great capabilities in real-time warn of the risky actions, rectification of wrong postures, and sports injury prevention.

Surface electromyography (sEMG) can provide multiplexed information about muscle performance. If current sEMG electrodes are stretchable, arrayed, and able to be used multiple times, they would offer adequate high-quality data for continuous monitoring. The lack of these properties delays the widespread use of sEMG in clinics and in everyday life. Here, we address these constraints by design of an adhesive dry electrode using tannic acid, polyvinyl alcohol, and PEDOT:PSS (TPP). The TPP electrode offers superior stretchability (~200%) and adhesiveness (0.58 N/cm) compared to current electrodes, ensuring stable and long-term contact with the skin for recording (>20 dB; >5 days). In addition, we developed a metal-polymer electrode array patch (MEAP) comprising liquid metal (LM) circuits and TPP electrodes. The MEAP demonstrated better conformability than commercial arrays, resulting in higher signal-to-noise ratio and more stable recordings during muscle movements. Manufactured using scalable screen-printing, these MEAPs feature a completely stretchable material and array architecture, enabling real-time monitoring of muscle stress, fatigue, and tendon displacement. Their potential to reduce muscle and tendon injuries and enhance performance in daily exercise and professional sports holds great promise.
