Flexible Parylene-based Microelectrode Technology for Intraocular Retinal Prostheses Damien C. Rodger*, pupil Member, IEEE, Wen Li, bookman Member, IEEE, Hossein Ameri, Aditi Ray, James D. Weiland, Member, IEEE, Mark S. Humayun, Member, IEEE, and Yu-Chong Tai, Senior Member, IEEE Abstract-We present the first whippy microelectrode arrays designed for intraocular implantation that utilize parylene C as their uncomplicated structural and insulating material. These electrodes are fabricated as a spring out component of an intraocular retinene prosthesis comprising a radio-frequency loop topology for author and entropy transfer, a bundled high lead-count telemetry-recovery and driving ASIC, and a high stringency epiretinal stimulating microelectrode array for the treatment of age-related blindness in humans. Electrochemical tests have demonstrated that these thin-film platinum electrodes behave through optim whollyy for neuronal stimulation. A novel ergonomic MEMS geom etry for a complete intraocular formation with capsular retaining wings that enables all the components of the system to be implanted and retained within the lens system contraction and vitreous cavity of the eye is also presented. The talent of this geometry when compared with a previous model without capsular retaining wings has been sustain by surgical implantation in animal models.

stress Low-resolution retinal prostheses have shown great promise in enabling subjects ruse from such diseases as retinitis pigmentosa and age-related macular degeneration to grasp visual data [1]. Few researchers contest the hypothesis that a higher density of electrod! es placed on the macula would generate the wearer a more useful visual map of the environment, likely restoring such abilities as facial recognition and coarse reading. This nextgeneration retinal prosthesis requires a high-density flexible retinal electrode array and cable, a flexible radio-frequency (RF) coil for wireless power and data recovery, and a high lead-count package for integration of...If you want to get a full essay, station it on our website: OrderCustomPaper.com
