Abstract

Highly sensitive strain sensors have been widely used in human motion monitoring, medical treatment, soft robots, and human–computer interaction, and the recycling of functional materials is in a huge demand for eco-friendly and sustainable electronics. However, the manufacturing of recyclable strain sensors still remains challenging. Here, a semi-wrapped structure based on silver nanowires and polyvinyl alcohol is proposed to realize a recyclable and stable strain sensor. It has shown excellent sensitivity, fast response, high stretchability and good environmental stability, and is successfully applied for human motion monitoring. In addition, a simple strategy is developed to effectively recycle silver nanowires in an eco-friendly manner. The recyclable and stable strain sensor demonstrates potential applications in wearable and stretchable electronics, and the recycling strategy can be extended to other noble metal nanomaterials.

基于聚乙烯醇中银纳米线半包裹结构的可回收稳定应变传感器，用于人体运动监测

高灵敏度应变传感器已被广泛应用于人体运动监测、医疗、软体机器人和人机交互等领域，而功能材料的回收利用也是环保和可持续电子产品的巨大需求。然而，可回收应变传感器的制造仍然充满挑战。本文提出了一种基于银纳米线和聚乙烯醇的半包裹结构，以实现可回收的稳定应变传感器。该传感器具有灵敏度高、响应速度快、伸缩性强和环境稳定性好等优点，并成功应用于人体运动监测。此外，还开发了一种以环保方式有效回收银纳米线的简单策略。这种可回收且稳定的应变传感器在可穿戴和可拉伸电子产品中具有潜在的应用前景，而且这种回收策略还可扩展到其他贵金属纳米材料。
