摘　　要：本文介绍的是一种基于微机电系统(MEMS)技术的表面型人工视网膜微电极阵列设计与仿真。电脉冲通过微电极刺激视网膜神经细胞,在大脑皮层视觉区域引起对应的特征电位反应,部分恢复患者的视觉。为研究表面型人工视网膜微电极阵列在人眼压力环境下的位移,特别设计了多种微电极阵列,进行了应力仿真。This paper introduces an artificial retina microelectrode array, which is based on the technique of microelectro mechanical system （MEMS）. As a part of stimulator, microelectrode arrays （MEA） were developed to stimulate the remained retina neurons and elicit an electrical-evoked response on the cortical region. To study the displacement of MEA under the stress of eye, different kinds of electrodes were designed and stress simulation was carried out in the design process.
