摘要：
近场通信（NFC）是一种有前途的技术，用于超低功耗可穿戴设备，但其短通信距离限制了其在狭窄区域点对点交互中的应用。我们提出了一种人体尺度NFC网络系统，扩展NFC覆盖范围以围绕身体，从而实现表面到多点的通信，通过分布式NFC传感器标签。本演示介绍了两种关键技术：Meander NFC和picoRing NFC。首先，Meander NFC扩展了基于服装的NFC网络区域，使其达到人体尺度，同时能够稳定读取占据覆盖区域1%的微型NFC标签。Meander NFC使用蛇形线圈，创建了沿纺织品表面的空间受限感应场，确保与小型标签的稳健耦合，同时防止不必要的电磁体耦合。第二，picoRing NFC解决了由于距离和尺寸不匹配导致的弱感应耦合。通过利用中距离NFC和线圈优化，picoRing NFC将通信范围扩展到连接环和腕带之间的这些异构节点。
英文摘要：
Near Field Communication (NFC) is a promising technology for ultra-low-power wearables, yet its short communication range limits its use to narrow-area, point-to-point interactions. We propose a body-scale NFC networking system that extends NFC coverage around the body, enabling surface-to-multipoint communication with distributed NFC sensor tags. This demonstration introduces two key technologies: Meander NFC and picoRing NFC. First, Meander NFC expands a clothing-based NFC networking area up to body scale while enabling a stable readout of small NFC tags occupying 1% of the coverage area. Meander NFC uses a meander coil which creates a spatially confined inductive field along the textile surface, ensuring robust coupling with small tags while preventing undesired electromagnetic body coupling. Second, picoRing NFC solves the weak inductive coupling caused by distance and size mismatches. By leveraging middle-range NFC and coil optimization, picoRing NFC extends the communication range to connect these disparate nodes between the ring and wristband.
