Abstract

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.

Description

technical field [0001] The invention relates to a stimulating electrode structure and an implantation device of artificial retina. Background technique [0002] 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 stimulating electrode is effectively attached to the stimulated part may greatly affect the stimulating effect of the stimulating electrode. [0003] For example, for the stimulating electrode array arranged on the retina, in order to allo...
