纺织集成超材料可用于沿多个物体以及在多个物体之间驱动基于近场通信的长距离磁感波，创建安全和按需的身体区域网络。可穿戴和可植入的传感器可以链接在一起，创建多节点无线网络，可用于开发先进的医疗监测技术。这样的身体区域网络需要安全、无缝和多功能的通信链路，可以在复杂的人体内运行，但它们通常存在距离短、功率低或需要直接连接终端的问题。在这里，我们展示了纺织集成的超材料可以用来驱动沿多个物体以及多个物体之间的基于长距离近场通信(NFC)的磁感应波。这种超材料由离散的、各向异性的磁感应元件阵列组成，创建了一个机械灵活的系统，能够在放置在靠近网络的任何地方的支持NFC的设备之间进行无电池通信。我们的方法提供了一个安全的按需身体区域网络，该网络具有直接扩展的潜力，可以跨越不同的衣服、物体和人。
Textile-integrated metamaterials can be used to drive long-distance near-field-communication-based magneto-inductive waves along and between multiple objects, creating a secure and on-demand body area network.Wearable and implantable sensors can be linked together to create multi-node wireless networks that could be of use in the development of advanced healthcare monitoring technologies. Such body area networks require secure, seamless and versatile communication links that can operate across the complex human body, but they typically suffer from short ranges, low power or the need for direct-connection terminals. Here we show that textile-integrated metamaterials can be used to drive long-distance near-field communication (NFC)-based magneto-inductive waves along and between multiple objects. The metamaterials are built from arrays of discrete, anisotropic magneto-inductive elements, creating a mechanically flexible system capable of battery-free communication among NFC-enabled devices that are placed anywhere close to the network. Our approach offers a secure and on-demand body area network that has the potential for straightforward expansion and can span across different pieces of clothing, objects and people.
