Many medical devices that are implanted in the body use wires or wireless radiofrequency telemetry to communicate with circuitry outside the body. However, the wires are a common source of surgical complications, including breakage, infection and electrical noise. In addition, radiofrequency telemetry requires large amounts of power and results in low-efficiency transmission through biological tissue. As an alternative, the conductive properties of the body can be used to enable wireless communication with implanted devices. In this article, several methods of intrabody communication are described and compared. In addition to reducing the complications that occur with current implantable medical devices, intrabody communication can enable novel types of miniature devices for research and clinical applications.
许多植入人体的医疗器械利用电线或无线射频遥测技术与体外的电路进行通信。然而,这些电线是导致手术并发症的常见原因,包括断裂、感染和电噪声。此外,射频遥测需要大量的电力,并且通过生物组织的传输效率较低。作为替代方案,可以利用人体的导电特性来实现与植入设备的无线通信。本文描述并比较了几种体内通信方法。除了减少当前可植入医疗设备所产生的并发症外,体内通信还可以实现用于研究和临床应用的新型微型设备。
