Engineers from the Federal Polytechnic School of Lausanne have invented a retinal implant that will restore sight to people. It will not be one hundred percent, but it will allow you to distinguish between specific objects from the environment.
Artificial retina has been created for a long time. But cyber materials have two drawbacks: a lot of pixels and a narrow angle of view. Now such implants do not allow you to navigate the terrain.
Communications Materials magazine writes that researchers from Switzerland have tried to solve this problem. They have developed a set of ultra-thin titanium electrodes that can be implanted into the retina. They can transmit signals to the retina from special glasses, which have a built-in microcomputer and digital camera.
These electrodes are deposited on a special thin flexible polymer substrate, the shape and size of which can be easily changed by stretching it in any way. Scientists tested their development on mice, as well as with the help of artificial retina analogs and diagnostic devices. It turned out that the cyber retina can effectively perceive flashes of light from glasses and transmit signals to the retina with pixel precision.
