Implant sensors and robots are expected to sense biological information or images. They stay in the human body for a long time to make a diagnosis or move freely inside the body to perform remote treatment, such as excision of the affected area or drug injection. In this study, toward the aforementioned purpose, we developed a communication module with small antennas that use the 10-60-MHz band to enable high-speed implant communication to the deep part of the human body. A waveform equalization technique was also used to increase the transmission bandwidth limited by the small antennas and reduce the sizes of their implementation. As a result, an implant communication distance of 33 cm or more that can cover the entire human torso was achieved at a data rate of 20 Mb/s. Experimental results on a living swine also showed that the developed module is able to communicate deeper in the human body than all others reported in the literature at sufficiently high data rates. This article describes the development of the implant communication module and shows the current status of research by comparing its performance with others reported in the literature.

开发深入人体的高速植入通信模块：通过小型天线在 10-60 MHz 频段实现 [生物电磁学]


植入传感器和机器人有望感知生物信息或图像。它们可以长时间留在人体内进行诊断或在体内自由移动以进行远程治疗，例如切除患处或注射药物。在本研究中，为了实现上述目的，我们开发了一种带有小型天线的通信模块，该模块使用10-60 MHz频段，能够实现与人体深层的高速植入通信。还使用波形均衡技术来增加受小型天线限制的传输带宽并减小其实施尺寸。结果，以 20 Mb/s 的数据速率实现了 33 厘米或更长的植入通信距离，可以覆盖整个人体躯干。对活猪的实验结果还表明，所开发的模块能够以足够高的数据速率比文献中报道的所有其他模块更深入地在人体内进行通信。本文介绍了植入物通信模块的发展，并通过将其性能与文献报道的其他模块进行比较来展示当前的研究现状。
