Design and Fabrication of Flexible Epi-retinal Microelectrode

Objectives To design and fabricate implantable epi-retinal microelectrode array for the purpose of retinal repair,and perform test on the features of the array.Methods With parylene as flexible substrate material and Pt as electrode material,monolayer microelectrode array was designed and fabricated,and electric characteristics of the array were measured with the three-electrode test system.Results Test results showed that morphological and electrochemical properties of the array met the design requirements.Conclusion The microelectrode array can be put in the in vivo electrophysiological experiments on animal.
