An artificial retina that could restore sight

Recommended Posts

Eldorado

"For more than a decade, researchers have been working to create artificial digital retinas that can be implanted in the eye to allow the blind to see again.

"Many challenges stand in the way, but researchers at Stanford University may have found the key to solving one of the most vexing: heat. The artificial retina requires a very small computer chip with many metal electrodes poking out.

"The electrodes first record the activity of the neurons around them to create a map of cell types. This information is then used to transmit visual data from a camera to the brain. Unfortunately, the eye produces so much data during recording that the electronics get too darn hot."
