本文提出了一种衣服上的身体传感器网络(BSN)，该网络由口袋中的智能手机无线供电。该网络由一个主机设备和多个传感器节点组成，这些节点分布在一个磨损上，并通过导电丝电连接。这款内置近场通信(NFC)功能的智能手机为固定在口袋中的主机供电。这些设备通过使用由插针和插座组成的特殊连接器连接到一块绣有导电线的特殊布料上，而不是一对一的布线。在拟议的BSN中，主机设备和智能手机通过口袋中的NFC无线电进行耦合。利用NFC无线电波收集能量需要将天线保持在几厘米以内以获得足够的功率。智能手机需要在口袋内定位和固定。所提出的主机设备可以通过使用多个天线和功率聚合电路来扩大能量收集的范围。实验结果证明了无电池BSNs系统的可行性。
This paper proposes a body sensor network (BSN) on clothing that is wirelessly powered by a smartphone in a pocket. The network consists of a host device and multiple sensor nodes, which are distributed on a wear and are electrically connected with conductive threads. The smartphone with a built-in near field communication (NFC) feature powers the host, which is fixed at the pocket. These devices are wired to a special cloth embroidered with conductive threads by using a special connector consisting of a pin & socket without one-to-one wiring. In the proposed BSN, the host device and the smartphone are coupled via NFC radio within the pocket. Energy harvesting with NFC radio wave requires maintaining antennas within several centimeters to obtain enough power. Positioning and fixing of the smartphone is required within the pocket. A proposed host device can expand the range of energy harvesting by using multiple antennas and a power aggregation circuit. The experimental results demonstrate the feasibility of the batteryless BSNs system.
