摘要

提出并分析了一种用于生物医学视网膜假体的无线供电系统。由于眼球运动引起的感应供电视网膜植入物的大而快速的耦合变化，必须控制过度的功率。这种功率传输设置通过眼睛模型的运动来实现过度功率控制测量。眼睛模型的转动由微控制器板控制。利用Matlab实现了模型的测量和控制自动化。测量结果显示，大眼球运动的传输功率大大降低，因此需要在生物医学植入物的功率控制。

Wireless power delivery for a biomedical retinal prosthesis

A wireless power delivery system for a biomedical retinal prosthesis is presented and analyzed. Due to large and fast coupling variations in the inductively powered retinal implant caused by the eye movements, excessive power has to be controlled. This power delivery setup enables excessive power control measurements by featuring movements of an eye model. The turning of the eye model is controlled with a microcontroller board. Measurements and control of the model is automatized using Matlab. Measurement results show an enormous reduction of the transmitted power for large eye movements and therewith the need for power control in biomedical implants.
