Hi am rohith i would like to get details on seminar report on artificial vision of a bionic eye ..My friend Justin said seminar report on artificial vision of a bionic eye will be available here and now i am living at kerala and i last studied in the college/school purappuzha
A visual prosthesis, often called a bionic eye, is an experimental visual device intended to restore functional vision in those who suffer from partial or total blindness. In 1983 Joao Lobo Antunes, Portuguese physician, implanted a bionic eye in a blind person of birth. Many devices have been developed, usually modeled in the cochlear implant or bionic hearing devices, a type of neural prosthesis in use since the mid-eighties. The idea of using electric current (for example, electrically stimulating the retina or the visual cortex) to provide sight dates back to the eighteenth century, discussed by Benjamin Franklin, Tiberius Cavallo and Charles LeRoy.
The bionic eye is an artificial electronic eye. The main objective of the bionic eye is to provide vision in part to visually impaired people by using modern electronic devices such as the Charge Coupled Camera (CCD) and Bionic Ocular Implant. The implant is a small chip that is implanted surgically behind the retina into the ball of the eye. It could restore sight of people who suffer from age-related blindness. There are two basic methodologies of the bionic eye, the artificial multiple retinal chip system (MARC) and the artificial silicon retinal system (ASR). However, this work presents a novel idea of integrating a new approach of the bionic eye with the nano-generator. The nano-generator is multifaceted compared to external batteries that provide better power, compactness and greater efficiency. The potential advantage of the proposed method is to eliminate blindness to a feasible extent by advancing the present investigation and improving manufacturing technology.
The bionic eye is a bio-electronic eye. The bionic eye replaces the functionality of part or all of the eye. An external camera is used on a pair of dark glasses that sends the images digitally to the radio receiver located in the eye. The radio receiver attaches to the implant chip in the retina. Implantation is of two types, epiretinal implant and sub-retinal implant, based on whether the implant is placed on or behind the retina. In our proposed bionic eye method, a small, powerful nano meter-fed camera is implanted into the patient's eye instead of using it in a pair of eyeglasses. The camera is small and consumes very little power.
