Scientists Have Made A Prototype “Bionic Eye” To Help Blind People See
By Jonathan O`Callaghan
Researchers say they have taken a big step towards creating a bionic eye that could help blind people see better in the future.
Published in the journal “Advanced Materials“ scientists from the University of Minnesota printed an array of light receptors on a hemispherical glass dome. They used a custom-built 3D printer to print a base of silver particles, and then printed photodiodes on top, which convert light into electricity.
This gave them a prototype “eye” that was 25 percent efficient at turning light into electricity. In theory, such a device could later be used to convert the real world into signals that could one day be interpreted by a person’s brain.
