| Summary: | 碩士 === 國立陽明大學 === 醫學工程研究所 === 98 === Objective：This research is design and fabricate the planar microelectrode array for the visual cortex. Look forward to record signals by light or electric stimulation from retina and this microelectrode. Furthermore, we improve the defects of penetrating microelectrode which could likely cause significant damage to blood vessels and cortical tissue and less using time. We hope that this research will become the pioneer in reconstructing visual signals.
Method：The planar microelectrode array in this research is employ MEMS process and the specification is refer to the form of penetrate. Using the surface processing method and process materials combined with the electrode material, surface shape, and structure design and fabricate the electrode.
Result：The planar microelectrode has been designed and fabricated in this paper. The specification are 8×8 array. The contact electrode size is 20μm diameter, and contact spacing is 200μm. We also design PCB to connect this microelectrode with analytical instruments.
Conclusion：This planar microelectrode array is using MEMS process and implement its function. Looking forward to replace the penetrate electrodes. Providing a tool for better safety and long-aging.
