设计了一种无线植入式传感器网络系统(WISNS)，用于活体监测动物种群的生理信号。WISNS可以同时监控15种以上的动物，在传感器节点之间传递三种模拟信息。模拟信号由AM以800-kHz载波传输到中继节点中继节点将其数字化并打包成消息，然后通过北欧射频技术(NWSN)转发到无线传感器网络。更小的整体尺寸(<；；2 cm3)、更低的功率调节和专用封装使该系统适用于植入式设备并与之兼容。通过大鼠心电监测实验，对可植入传感器节点、无线传感器网络协议栈以及系统性能进行了评估和优化。与商业上可用的传感器节点相比，我们的植入式传感器节点在重量和体积小型化方面处于领先地位，我们的WISNS解决方案在实现不同动物的兼容性方面显示出巨大的潜力。
A wireless implantable sensor network system (WISNS) is designed for in vivo monitoring physiological signals of a population of animals. WISNS can simultaneously monitor more than 15 animals, communicating three kinds of analog information among sensor nodes. Analog signals are transmitted to relay node at 800-KHz carrier by AM. Relay nodes digitalize and package them into messages, and then forward to the Wireless sensor network by Nordic RF technology (NWSN). Smaller overall dimensions (<;2 cm3), lower power regulation, and dedicated packaging make the system suitable and compatible for implantable devices. The implantable sensor node, protocol stack of NWSN, and performance of the system are evaluated and optimized with ECG monitoring test of rats. Compared with those commercially available sensor nodes, our implantable one is leading in the weight and volume miniaturization, and our WISNS solution shows huge potential in achieving the compatibility of different animals.
