A mechanically flexible textile antenna-backed sensor node is designed and manufactured, providing accurate personal localization functionality by application of Decawave’s DW1000 Impulse Radio Ultra-Wideband (IR-UWB) Integrated Circuit (IC). All components are mounted on a flexible polyimide foil, which is integrated on the backplane of a wearable cavity-backed slot antenna designed for IR-UWB localization in Channels 2 and 3 of the IEEE 802.15.4-2011 standard (3744 MHz–4742.4 MHz). The textile antenna’s radiation pattern is optimized to mitigate body effects and to minimize absorption by body tissues. Furthermore, its time-domain characteristics are measured to be adequate for localization. By combining the antenna and the bendable Printed Circuit Board (PCB), a mechanically supple sensor system is realized, for which the performance is validated by examining it as a node used in a complete localization system. This shows that six nodes around the body must be deployed to provide system coverage in all directions around the wearer. Even without using sleep mode functionalities, the measurements indicate that the system’s autonomy is 13.3 h on a 5 V 200 mAh battery. Hence, this system acts as a proof of concept for the joining of localization electronics and other sensors with a full-textile antenna into a mechanically flexible sensor system.

ully灵活的纺织天线支持的传感器节点，可用于穿戴式UWB定位

设计并制造了具有机械柔性的纺织天线支持的传感器节点，通过应用Decawave的DW1000脉冲无线电超宽带（IR-UWB）集成电路（IC）提供准确的个人定位功能。所有组件均安装在柔性聚酰亚胺箔片上，该箔片集成在可穿戴腔背式缝隙天线的背板上，该缝隙天线旨在用于IEEE 802.15.4-2011标准（3744 MHz–4742.4 MHz）的IR-UWB本地化）。优化了纺织天线的辐射方向图，以减轻人体影响并使人体组织的吸收最小化。此外，测得其时域特性足以进行定位。通过将天线和可弯曲印刷电路板（PCB）组合在一起，可以实现机械柔顺的传感器系统，通过将其作为完整的本地化系统中使用的节点进行检查，可以验证其性能。这表明必须在身体周围部署六个节点，以在穿戴者周围的所有方向提供系统覆盖。即使不使用睡眠模式功能，这些测量也表明，使用5 V 200 mAh电池时，系统的自治时间为13.3小时。因此，该系统可作为将带有全纺织天线的定位电子设备和其他传感器连接到机械柔性传感器系统中的概念证明。使用5 V 200 mAh电池3小时。因此，该系统可作为将带有全纺织天线的定位电子设备和其他传感器连接到机械柔性传感器系统中的概念证明。使用5 V 200 mAh电池3小时。因此，该系统可作为将带有全纺织天线的定位电子设备和其他传感器连接到机械柔性传感器系统中的概念证明。
