Weiland, Member, IEEE, Mark S. Humayun, Member, IEEE, and Yu-Chong Tai, Senior Member, IEEE Abstract-We present the first flexile microelectrode arrays designed for intraocular implantation that utilize parylene C as their simple(a) structural and insulating material. These electrodes are fabricated as a reap out component of an intraocular retinene prosthesis comprising a radio-frequency gyrate 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 for through optim ally for neuronal stimulation. A novel ergonomic MEMS geo metry for a complete intraocular formation with capsular retaining wings that enables all the components of the system to be implanted and retained within the lense 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 corroborate by surgical implantation in animal models. play down 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 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-co! unt package for integration of...If you want to get a full essay, station it on our website: BestEssayCheap.com
