Abstract：Considering the structure characteristics and implanting requirements of retina microelectrode array,the key component of retinal prosthesis,implantable epi -retinal Au microelectrode array based on Parylene -C with a diameter of 200 μm were designed and fabricated.To measure electrochemical characteristics of the microelecrode array,electrochemical impedance spectroscopy (EIS) were peformed with the three -electrode test system.Results showed that morphological and electrochemical properties of the flexible gold electrode could meet the requirements of retinal stimulating electrodes.With it,a low cost and simplified manufacturing design of retinal microelectrode can be used in vivo electrophysiological experiments on animals.
