用于人工视网膜的刺激电极结构
摘要：
本发明提供了一种用于人工视网膜的刺激电极结构，其包括：绝缘衬底，其由具有生物兼容性的柔性材料构成；以及多个刺激电极，其设置在绝缘衬底中，并且构成沿着与绝缘衬底平行的二维方向排列的阵列体，刺激电极从绝缘衬底的表面突起，各个刺激电极包括基部段和露出段，各个刺激电极的电极高度等于基部段的高度与露出段的高度之和，多个刺激电极的各个刺激电极的电极高度大致相同，多个刺激电极的各个刺激电极的露出段从阵列体的中央向阵列体的边缘逐渐减小。在本发明所涉及的人工视网膜的电极阵列中，既形成了由三维刺激电极构成的阵列体，同时也降低了刺激电极之间的阻抗差异，从而能够更加有效地对视网膜进行刺激。
摘要（英）：

The invention provides a stimulating electrode structure. The stimulating electrode structure comprises an insulated substrate and a plurality of stimulating electrodes arranged in the insulated substrate and forming an array body arranged in a two-dimensional direction parallel to the insulated substrate, wherein the stimulating electrodes protrude from the surface of the insulated substrate; electrode heights of the stimulating electrodes are roughly same; and the electrode distances between the stimulating electrodes and the surface of the insulated substrate are gradually reduced from the center of the array body to the edge of the array body. According to the stimulating electrode structure, in an electrode array of an artificial retina, the array body composed of the three-dimensional stimulating electrodes is formed and the impedance difference between the stimulating electrodes is reduced, so that the retina can be stimulated more effectively.
