在本文中，我们提出了使用超声波的电源和双向信息传输系统。超声波不会干扰植入设备的电子电路，对生命体是安全的。此前，我们已经通过实验阐明超声波适用于电力和信息传输。这项研究涉及提高从身体内部到外部的信息传输速度。新系统使用两条传输路径：路径 1 和路径 2。每条路径均由一对压电振荡器组成。路径 1 传输载波，路径 2 回显内部信息。结果，传输速度从 600 bps 提高到 9.6 Kbps，且没有错误。此外，还可以传输多种类型的信息，例如文本、静态和运动图像文件。所提出的系统可以应用于各种医疗应用。
In this paper, we propose the power supply and the bi-directional information transmission system using ultrasonic. Ultrasonic does not interfere with the electronic circuits of implanted devices and is safe for a living body. Previously, we have clarified experimentally that ultrasonic is applicable to power and information transmission. This study deals with improving information transmission speed from the inside to the outside of the body. The new system uses two transmission paths, Path 1 and Path 2. Each path consists of a pair of piezo oscillators. Path 1 transmits a carrier wave and Path 2 echoes back the inside information. As a result, the transmission speed increases to 9.6 Kbps from 600 bps without errors. Additionally, several types of information, such as text, static and motion image files can be transmitted. The proposed system can be applied to various medical applications.
