AI 中文摘要
无电池RFID系统提供了一种可扩展且无需维护的交互方式。我们展示了KnitID，一种机器编织的纺织RFID天线设计，可实现身体认证、定位和交互。与先前的天线设计不同，KnitID通过将电磁线集成到机器编织独特的环套环结构中，实现了紧凑的天线外形尺寸（60毫米×8毫米）。这种结构将传统环形天线的尺寸减小了约90%，同时在人体上比类似尺寸的标准偶极设计的感应范围长30%。紧凑的外形为在人体上嵌入多个RFID标签创造了新机会，丰富了反向散射信号并支持更广泛的无电池身体交互。为证明这种能力，我们构建了一个交互式袖子来支持佩戴者认证、空间定位和交互检测。通过技术评估，我们展示了KnitID在编织用户界面上提供多样化无电池交互的可行性。
英文摘要
Battery-free RFID systems offer a scalable and maintenance-free approach to interaction. We present KnitID, a machine-knitted textile RFID antenna design that enables on-body authentication, localization, and interaction. Unlike prior antenna designs, KnitID achieves a compact antenna form factor (60mm by 8mm) by integrating magnet wire into the unique loop-over-loop structure of machine knitting. This structure reduces the size of conventional loop antennas by around 90\%, while also providing 30\% longer sensing ranges than standard dipole designs with similar size on the human body. The compact form factor creates new opportunities to embed multiple RFID tags across the human body, enriching backscatter signals and supporting a broader range of battery-free on-body interactions. To demonstrate this capability, we build an interactive sleeve to support wearer authentication, spatial localization, and interaction detection. Through technical evaluations, we show the feasibility of KnitID to provide diverse and battery-free interactions on knitted user interfaces.
