Recently, an investigation into preventive measures for coronavirus disease 2019 (COVID-19) has garnered considerable attention. Consequently, strategies for the proactive prevention of viral pathogens have also attracted significant interest in the field of wearable devices and electronic textiles research, particularly due to their potential applications in personal protective equipment. In this study, we introduce smart textiles designed with optimized piezoelectric devices that exhibit antifouling performance against microorganisms and actively inactivate viruses. These active-type smart textiles, which incorporate advanced lead zirconate titanate (PZT) ceramics, a stretchable interconnector array, and polymeric fabric, demonstrate effective antifouling capabilities, detaching approximately 90% of Escherichia coli and 75% of SARS-CoV-2. Furthermore, they inactivate viruses, releasing ~26.8 ng of N protein from ruptured SARS-CoV-2, using ultrasonic waves within the wearable platform. Experimental results show that piezoelectric smart textiles significantly reduce the spread of COVID-19 by leveraging the electrical and acoustic properties of PZT ceramics.

最近，对 2019 冠状病毒病 （COVID-19） 预防措施的调查引起了相当大的关注。因此，主动预防病毒病原体的策略也引起了可穿戴设备和电子纺织品研究领域的浓厚兴趣，特别是因为它们在个人防护设备中的潜在应用。在这项研究中，我们介绍了采用优化的压电器件设计的智能纺织品，这些器件对微生物表现出防污性能并主动灭活病毒。这些活性型智能纺织品采用先进的锆钛酸铅 （PZT） 陶瓷、可拉伸互连器阵列和聚合物织物，表现出有效的防污能力，可去除约 90% 的大肠杆菌和 75% 的 SARS-CoV-2。此外，它们在可穿戴平台内使用超声波灭活病毒，从破裂的 SARS-CoV-2 中释放出 ~26.8 ng 的 N 蛋白。实验结果表明，压电智能纺织品通过利用 PZT 陶瓷的电学和声学特性显着减少了 COVID-19 的传播。
