植入微型传感器和执行器的生物医学系统连接到体内区域网络中，可以彻底改变折磨内脏的慢性疾病的治疗选择。考虑到射频（RF）在人体内传播的局限性，我们已经探索了磁共振（MR）耦合在体内的通信和能量传递。在本文中，我们讨论了使用通用软件无线电外设（USRP）板的软件定义原型的设计和实现。我们报告了在不同位置通过身体的距离和数据包大小所获得的数据包错误率的实验结果。我们通过实验观察到，MR信号在体内的传播比在空气中的传播要好得多，并且可以为体内网络中的能量传递和通信提供实用的手段。它也比更好理解的电偶更有效。
Biomedical systems of implanted miniaturized sensors and actuators interconnected into an intra-body area net-work could revolutionize treatment options for chronic diseases afflicting internal organs. Considering the well-understood limitations of radio frequency (RF) propagation in the human body, we have explored magnetic resonance (MR) coupling for both communications and energy transfer through the body. In this paper, we have discussed the design and implementation of a software-defined prototype using Universal Software Radio Peripheral (USRP) boards. We have reported experimental results on the achieved packet error rates at different positions through-the-body distances and packet sizes. We have observed experimentally that the MR signal propagates through the body substantially better than in the air, and can provide a practical means for energy transfer and communications in intra-body networks. It also works better than the better understood galvanic coupling.
