The development of wearable electronic skins (E-skins) requires devices with high flexibility, breathability, and antibacterial activity, as in sports sensing technology. Here, we report a flexible, breathable, and antibacterial triboelectric nanogenerator (TENG)-based E-skin for self-powered sensing in volleyball reception statistics and analytics, which is fabricated by sandwiching a silver nanowire (Ag NW) electrode between a thermoplastic polyurethane (TPU) sensing layer and a poly(vinyl alcohol)/chitosan (PVA/CS) substrate. Benefiting from an outstanding breathability of 10.32 kg m^–2 day^–1 and biocidal properties of CS and Ag NW, the E-skin offers excellent thermal-moisture comfort and a remarkable antibacterial effect on Escherichia coli and Staphylococcus aureus. A pressure sensitivity of 0.3086 V kPa^–1 is demonstrated in the sensing range of 6.65–19.21 kPa. Besides, a volleyball reception statistical and analytical system is further developed based on a 2 × 3 E-skin array. According to this work, the integration of wearable electronic devices with self-powered sensors may expand practical applications in sports.

面向自供电传感运动系统的集成全纤维电子皮肤

可穿戴电子皮肤（E-skins）的发展需要具有高柔韧性、透气性和抗菌活性的设备，如运动传感技术。在这里，我们报告了一种灵活、透气和抗菌的基于摩擦电纳米发电机 (TENG) 的电子皮肤，用于排球接收统计和分析中的自供电传感，它是通过将银纳米线 (Ag NW) 电极夹在热塑性聚氨酯之间制成的(TPU) 传感层和聚乙烯醇/壳聚糖 (PVA/CS) 基板。得益于 10.32 kg m ^–2 day ^–1的出色透气性和 CS 和 Ag NW 的杀菌特性，E-skin 提供出色的热湿舒适性和对大肠杆菌和金黄色葡萄球菌。在 6.65–19.21 kPa的感应范围内显示了0.3086 V kPa ^{–1的压力灵敏度。}此外，还进一步开发了基于2×3 E-skin阵列的排球接球统计分析系统。根据这项工作，可穿戴电子设备与自供电传感器的集成可能会扩展运动中的实际应用。
