Researchers say they’ve created a proof-of-concept bionic eye that could surpass the sensitivity of a human one.
“In the future, we can use this for better vision prostheses and humanoid robotics,” researcher Zhiyong Fan, at the Hong Kong University of Science and Technology, told Science News.
The eye, as detailed in a paper published in the prestigious journal Nature today, is in essence a three dimensional artificial retina that features a highly dense array of extremely light-sensitive nanowires.
The team, led by Fan, lined a curved aluminum oxide membrane with tiny sensors made of perovskite, a light-sensitive material that’s been used in solar cells.
Wires that mimic the brain’s visual cortex relay the visual information gathered by these sensors to a computer for processing.
