The present disclosure relates to a microneedle array-based electrode comprising organic photovoltaic substances, and an artificial retina device comprising the same, and the microneedle array-based electrode is coated with, as organic photovoltaic substances, a mixture of PCE10, which exhibits the highest absorbance in infrared rays, and ITIC, thereby exhibiting excellent photovoltaic efficiency and low phototoxicity. Further, since an artificial retina device comprising the electrode can adjust the generation of current only with light without any wire connecting the inside and outside of the eyeball, it is possible to restore nerve signals by stimulating the retina of a patient whose photoreceptor cells are damaged.

Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.
