摘要
随着科学技术的发展,神经假体已经在神经修复医学工程中得到广泛应用,以解决单纯依靠药物和手术方法等难以治疗的难题。由于神经假体的部分植入性和实时处理性,能量和数据传输是神经假体的重要组成部分之一,在很大程度上决定了神经假体的实用价值。文中介绍了神经假体及其能量供给方式、体内外通信的研究现状和进展,尤其重点论述了电磁感应高效传输能量采用的电磁耦合和E类放大器的设计、为避免双频段传输能量和数据之间电磁干扰所采用的线圈设计和数据调制的选择,以及反映体内状态信息以便监控的反向数据传输。
Neural prostheses have been widely used in nerve repair medical engineering,and have resolved problems which are difficult to cure solely by drugs or surgical methods.As neural prostheses are partially implanted and need real time processing,energy and data transmission is an important part of neural prostheses,determining the practical utility of the prostheses to a large extent.This review introduced neural prostheses,the current work and development of energy supplement and the communications in vivo and in vitro.And we particularly emphasized the design of electromagnetic coupling and the Class-E amplifier for highly efficient inductive power transfer,the coil design and the choice of data modulation adapted to avoid the mutual electromagnetic interference in the dual band power and data telemetry,and the reverse data transmission which indicates the information in vivo for monitoring.
