讲座摘要/Abstract:

可穿戴电子设备在实现健康监测与康复、物联网、软机器人等方面发挥着重要作用。这些可穿戴设备和系统应该高度灵活，可伸缩，甚至可清洗。并且，应该保持长时间穿着舒适。本讲座将讨论导电纺织材料的最新发展及其在可穿戴电子产品中的应用。尤其是，我们将讨论1)通过聚合物辅助金属沉积(PAMD)开发高导电、柔韧性和可洗性的导电纤维、纱线和织物，可广泛用于可穿戴感官和储能用途; 2)开发高渗透性可拉伸导体，即液态金属纤维垫(LMFM)，使它长期可穿戴以及3D整体可拉伸电子产品成为可能。

Wearable electronics plays an important role in the realization of health monitoring and rehabilitation, Internet of Things (IoTs), and soft robotics. These wearable devices and systems should be highly flexible, stretchable and even washable. In addition, they should be comfortable to wear in a long term. This talk will discuss the recent development of conductive textile materials and their applications in wearable electronics. In particular, we will discuss 1) the development of highly conductive, flexible and washable conductive fibers, yarns and fabrics through polymer-assisted metal deposition (PAMD), that can be used for a wide range of wearable sensory and energy-storage uses; and 2) the development of highly permeable stretchable conductors, namely liquid metal fiber mat (LMFM), which enables long-term wearable and 3D monolithic stretchable electronics.
