Stretchable conductive yarns have received significant consideration in the direction of wearable and flexible electronics. Wearable electronic structures need strong materials to assure stability, durability, and an extensive range of strain to develop their applications. Therefore, manufacturing high-performance yarn-based devices with ultrarobustness and great stretchability with a simple, cost-effective, and scalable method remains a great challenge for wearable electronics. Here, a highly stretchable yarn with high performance is fabricated, which comprises a core TPU nanoyarn, successively decorated with a liquid metal (LM) layer, and a protective outer nanofiber layer. The ultrarobust (40 MPa) and high-strain (548%) conducting yarn presents potential applications in assembling strain sensors. Moreover, such a unique conductive yarn can be used as a highly deformable, stretchable conductor to charge a mobile phone or for data transfer, a sensor to monitor human activities, and as an effective control for a hand robot as well as for smart thermal management textile application. This research gives promising applications in the field of flexible and wearable electronics.

用于可穿戴电子产品的高强度和可延展电纺纱

在可穿戴和柔性电子产品的方向上，可拉伸的导电纱线已经得到了重要的考虑。可穿戴电子结构需要坚固的材料来确保稳定性、耐用性和广泛的应变范围以开发其应用。因此，以简单、经济高效和可扩展的方法制造具有超强韧性和高拉伸性的高性能纱线基设备仍然是可穿戴电子设备面临的巨大挑战。在这里，制造了一种高性能的高拉伸纱线，它包括芯 TPU 纳米纱线，依次装饰有液态金属 (LM) 层和保护性外层纳米纤维层。超坚固 (40 MPa) 和高应变 (548%) 的导电纱线在组装应变传感器方面具有潜在应用。而且，这种独特的导电纱线可用作高度可变形、可拉伸的导体，为手机充电或用于数据传输、监测人类活动的传感器，以及作为手动机器人的有效控制以及智能热管理纺织品应用. 这项研究在柔性和可穿戴电子产品领域提供了有希望的应用。
