我们介绍了一种新的无线植入遥测系统，利用磁感应波导（MIW）打破国家的最先进的边界方面：（a）传输损耗，和（B）带宽。磁感应波导依赖于一系列谐振回路的精心设计，其中发射回路上的激励电流导致电流作为磁感应波传播到接收回路。MedRadio（401-406 MHz）MIW与1 cm深度的49.3 mm 3植入体通信，传输损耗仅为19.4 dB，带宽为187.4 MHz。这表示与类似的基于射频（RF）的系统相比，改进超过30 dB和85 MHz。值得注意的是，报告的MIW框架授权了一个完整的可穿戴系统，该系统可以集成到衣服中，以处理放置在人体上和人体内的无线节点。
We introduce a novel wireless implant telemetry system that utilizes magnetoinductive waveguides (MIW) to break state-of-the-art boundaries in terms of: (a) transmission loss, and (b) bandwidth. Magnetoinductive waveguides rely on the careful design of a series of resonant loops, where excited current on the transmit loop leads to the current propagating as magnetoinductive waves to the receive loop. A MedRadio (401–406 MHz) MIW is shown to communicate with a 49.3 mm3 implant at 1 cm depth with a transmission loss of only 19.4 dB and a bandwidth of 187.4 MHz. This represents an improvement of over 30 dB and 85 MHz over a similar Radio-Frequency (RF) based system. Notably, the reported MIW framework empowers a full wearable system that can be integrated into clothing to handle wireless nodes placed both on and inside the human body.
