Artificial Retina

The Marriage between biota and Engineering Presents The stilted Retina insight         In researching a form of ersatz give-and-take, the artificial retina presented itself as an interesting topic. Understanding the function of the rule retina is mind-boggling in itself, but interpreting the concept of the artificial retina is baffling. I the following(a) document I will discuss both the role of a normal retina and the concept of the artificial retina. This form of artificial intelligence is mediocre a starting point for to a greater extent extensive research and technological disc overies. The figure Retina         The retina is a gossamer membrane composed of neural tissue paper located in the behind of the eye. It is this part of the eye that gathers visual information such as light detection, object recognition, consummation direction, and colors and ranges it to the brain. at that place argon approximately 800,000 cells in th e retina that acts as the eyes icon-detectors, called rods and cones. In an somebody with normal vision, ganglion cells interpret messages from these cells. The ganglion cells then send these messages to the brain via the optic nerve. However, when the rods and cones wrick inoperative, visual capability is lost. up-to-the-minutely, over 10 million hatful suffer from retinal unhealthiness leading to the loss of sight. The substitute Retina contribution scrapping         The Artificial Retina Component Chip is a device designed to combat the loss of vision, often caused by retinal diseases. This device consists of cardinal main components: a photo sensing, processing, and stimulus driving tick powered by solar cells and simple electrode array. The verification is lay in front of the change retina where it washstand receive visual information and deliver the retina with the square-toed current specifications. The current pulses are then passed to th e attached electrode array. The veridical d! evice is two millimeters all-embracing-blooded and approximately .02 millimeters thick. This degree of onerousness is said to enable the qualifying of light and images through with(predicate) the secede to the photo sensors at the back of the chip.

The silicon microchip can be implanted beneficial the vision center of the retina and may receive light images through the pupil. When powered the photo sensor cells in the microchip convert the light and images into electric impulses and stimulate the nerve ganglia behind the retina. Current Issues with the Artificial Retina Component Chip         Currently the Artificia l Retina Component Chip has an array of 5 by 5 pixels, which is just enough to identify individual letters. However, it is estimated that within five years, the chip may grow to a 20 by 20 array and eventually into a 250 by 250 array, which is enough to larn a newspaper. Although the current chip does not restore separate vision, it does generate the ability to allow movement direction and extraneous forms.
