Flexible Parylene-based Microelectrode Technology for Intraocular Retinal Prostheses Damien C. Rodger*, pupil Member, IEEE, Wen Li, savant 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 pliant microelectrode arrays designed for intraocular implantation that utilize parylene C as their childlike structural and insulating material. These electrodes are fabricated as a amaze out component of an intraocular retinene prosthesis comprising a radio-frequency looping 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 stick out through optim wholey for neuronal stimulation. A novel ergonomic MEMS geometry 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 contraction and vitreous cavity of the eye is also presented. The skill of this geometry when compared with a previous model without capsular retaining wings has been substantiate by surgical implantation in animal models.

footing Low-resolution retinal prostheses have shown great promise in enabling subjects ruse from such diseases as retinitis pigmentosa and age-related macular degeneration to observe visual data [1]. Few researchers contest the hypothesis that a higher density of electrodes placed ! on the macula would present the wearer a more useful visual map of the environment, possible 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: BestEssayCheap.com
