A Solar-Powered Artificial Eye Has Been Developed

Scientists have succeeded in creating an artificial eye with features similar to the structure of the human eye. The robot, which successfully completes the tests on the computer, will work with solar energy.

Scientists have developed an artificial eye that mimics the structure of the human eye and is powered by solar energy. A new study by Zhiyong Fan & a team from the Hong Kong University of Science and Technology could be a beacon of hope for visually impaired people. The artificial eye, which has a robotic structure, contains a lens that focuses light and a hemispherical retina behind the eye that produces electrical impulses sent to the brain by light-sensitive cells. The artificial eye is the same size as an adult eye and is filled with a transparent gel.

The artificial retina is made of porous aluminum oxide filled with densely packed nanowires. These wires are made from a compound called photosensitive perovskite, which is commonly used in solar cells. They act similarly to nerve cells in the human eye and are activated by light and transmit electrical signals. Successfully recognizes the letters E, I and Y, which are of particular importance in an eye-catching computer programming. The team says the device could be connected to an optical nerve instead of a computer to see if it is medically safe. If the team successfully connects the artificial eye to the optic nerve, it can improve the future of blind people.

We hope this and similar studies will gain momentum and disability, which is one of the sources of discrimination in the world, will also disappear.
