Abstract

The present invention provides a stimulation electrode structure for an artificial retina. The structure comprises an insulating substrate which is formed by a flexible material with biological compatibility, and a plurality of stimulation electrodes which are arranged in the insulating substrate and form an array body which is arranged along a two-dimensional direction parallel to the insulating substrate. The stimulation electrodes protrude from the surface of the insulating substrate. Each of the stimulation electrodes comprises a base section and an exposed section. The electrode height of each stimulation electrode is equal to a sum of the height of the base section and the height of the exposed section, the heights of the stimulation electrodes are roughly the same, and the exposed sections of the stimulation electrodes are gradually reduced from the center of the array body to the edge of the array body. In the electrode array of the artificial retina in the invention, the array body formed by three dimensions of stimulation electrodes, at the same time the impedance difference between the stimulation electrodes is reduced, and thus the retina can be more effectively stimulated.

Description

[0001] This application is a divisional application of a patent application with an application date of August 1, 2016, an application number of 201610624835.3, and an invention titled Stimulating Electrode Structure and Artificial Retina Implantation Device. technical field [0002] The invention relates to a stimulating electrode structure for artificial retina. Background technique [0003] In the field of neurostimulation, stimulating electrodes or stimulating electrode arrays are often used as stimulating components to directly act on nerve regions, such as the myocardium of the heart, the deep part of the brain (deep brain), the retina in the eyeball, etc. Electrically stimulating these neural regions through stimulating electrodes or stimulating electrode arrays can cause these neural regions to generate corresponding neural feedback, thereby obtaining expected biological effects such as light perception and the like. In the above stimulation process, whether the stim...
