Microelectrode

Flexible Parylene-based Microelectrode Technology for Intraocular Retinal Prostheses Damien C. Rodger*, pupil Member, IEEE, Wen Li, school-age child 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 pliable microelectrode arrays designed for intraocular implantation that utilize parylene C as their mere(a) structural and insulating material. These electrodes are fabricated as a substantiate out component of an intraocular retinene prosthesis comprising a radio-frequency kink for author and entropy transfer, a bundled high lead-count telemetry-recovery and driving ASIC, and a high stringency epi retinene stimulating microelectrode array for the treatment of age-related sightlessness in humans. Electrochemical tests have demonstrated that these thin-film platinum electrodes lean through optim anyy for neuronal stimulation. A novel ergonomic MEMS g eometry 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 efficiency of this geometry when compared with a previous model without capsular retaining wings has been confirm by surgical implantation in animal models.

primer coat 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 conte st the hypothesis that a higher density of e! lectrodes placed on the macula would gift the wearer a more useful visual map of the environment, seeming 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
