中文摘要：

提高视觉假体的空间分辨率是增强假体植入者视觉感受的直接有效的方法。然而随着假体装置可植入电极数目的增加．假体装置的功耗也大幅增长。针对这种发展趋势，视觉假体需要实现大功率、高效率的无线能量传输和高速率的数据传输。该文回顾了视觉假体无线传输研究的现状和面临的挑战，分析了其工作原理和设计要求，进而针对其特点分别介绍了能量传输和数据传输的设计方法。

英文摘要：

Boosting spatial resolution of visual prostheses is an effective method to improve implant subjects visual perception. However, power consumption of visual implants greatly rises with the increasing number of implanted electrodes. In respond to this trend, visual prostheses need to develop high-efficiency wireless power transmission and high-speed data transmission. This paper presents a review of current research progress on wireless power and data transmission for visual prostheses, analyzes relative principles and requirement, and introduces design methods of power and data transmission.
