A new artificial retina prevents dangerous overheating by selectively ignoring redundant data.
In typical artificial retinas, the visual information must be digitized and then compressed for communication with the neurons in two separate steps—which generates heat in the form of electrical impulses. However, the new design by the team from Stanford University is able to detect and ignore identical signals, considered noise, and digitize only the important information. This innovation reduced the data acquired by 40 times.
According to postdoctoral researcher Dante Muratore,“This is an important step that might someday allow us to build a digital retina with over 10,000 channels."
