电流耦合已被证明是低功耗在体数据传输的最佳方法。这种方法已扩展到植入设备之间的无线通信，构建真正的体内传感器网络。为了证明可行性，开发并实施了测试系统。将测量结果与数值模拟进行比较。该原型提供四个并发通道，吞吐量为 4.8 kb/s。主要关注点是未来植入这种小型系统，用于对患者进行长期医疗监测。为了实现这一目标，必须仔细考虑小电路尺寸、低功耗和电气安全。
Galvanic coupling has been shown to be the best method for low-power on-body data transmission. This approach has been extended toward wireless communication between implanted devices, building a real intrabody sensor network. To show the feasibility, a test system has been developed and implemented. The measurements are compared with the numerical simulations. The prototype offers four concurrent channels with a throughput of 4.8 kb/s. The main focus is the future implantability of such a miniaturized system for the medical long-term surveillance of patients. To achieve this goal, small circuit size, low power consumption, and electrical safety have to carefully be considered.
