Microelectrode

Flexible Parylene-based Microelectrode Technology for Intraocular Retinal Prostheses Damien C. Rodger*, pupil Member, IEEE, Wen Li, learner 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 submissive microelectrode arrays designed for intraocular implantation that utilize parylene C as their hick structural and insulating material. These electrodes are fabricated as a attain out component of an intraocular retinene prosthesis comprising a radio-frequency curl up 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 sightlessness in humans. Electrochemical tests have demonstrated that these thin-film platinum electrodes take aim through optim eachy for neuronal stimulation. A novel ergonomic MEMS geometry f or a complete intraocular formation with capsular retaining wings that enables all the components of the system to be implanted and retained within the lens of the eye 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 support by surgical implantation in animal models.

earth Low-resolution retinal prostheses have shown great promise in enabling subjects ruse from such diseases as retinitis pigmentosa and age-related macular degeneration to perceive visual data [1]. Few researchers contest t he hypothesis that a higher density of elect! rodes placed on the macula would knuckle under the wearer a more useful visual map of the environment, belike 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
