体内通信（IBC）这一新兴领域将通过允许人体受试者的原位监测和移动性来带来许多医疗保健应用的创新。我们使用一种称为电流耦合 (GC) 的技术，该技术使用弱电流而不是射频来进行体内链接，因为在比较能源效率时，这要高出两个数量级。在这项工作中，我们演示了一种实验装置，可用于使用现成的硬件和商业采购的合成人体组织来实现和验证物理层通信方案和链路层协议。我们的设置使用通用软件无线电外围设备 (USRP) 作为发射器和接收器节点，并带有附加的接口电子设备，以允许在 100 kHz - 1 MHz 频率范围内灵活传输信号。此外，我们还提供基于 GUI 的可视化配置以及基于链路质量结果的演示。完整的硬件和软件设计以及教学视频无需许可即可供公众使用，以促进该领域的进一步研究。
The emerging field of Intra-Body Communication (IBC) will result in the innovation of many health care applications by allowing in-situ monitoring and mobility for the human subjects. We use a technique called Galvanic Coupling (GC) that uses weak electrical currents for the intra-body links, instead of RF, as this is two orders of magnitude superior when comparing energy efficiency. In this work, we demonstrate an experimental setup that can be used to implement and validate physical layer communication schemes and link layer protocols using off-the-shelf hardware and commercially procured synthetic human tissue. Our setup uses Universal Software Radio Peripherals (USRPs) as the transmitter and receiver nodes, with additional interfacing electronics, to allow flexible transmission of signals in the 100 kHz - 1 MHz frequency range. Furthermore, we provide a visual GUI-based configuration as well as demonstration of link quality based results. The complete hardware and software design, as well as an instructional video, are made available license-free for public consumption to stimulate further research in this field.
