Bionic Eye With Better Vision Than Humans
The world’s first 3D artificial eyeball — capable of outperforming the human eye in some ways — may help droves of people who are partially or fully blind in as little as five years, according to experts.
Researchers from Hong Kong University of Science and Technology have devised an electrochemical eye whose structure and performance mimic those of the ones humans are born with.
“The device design has a high degree of structural similarity to a human eye with the potential to achieve high imaging resolution when individual nanowires are electrically addressed,” researchers of Hong Kong University of Science and Technology wrote in a paper published in the journal Nature.
The device converts images through tiny sensors that mirror the light–detecting photoreceptor cells in a human eye, The Sun reported. Those sensors reside within a membrane made of aluminum and tungsten which is shaped into a half sphere for the purpose of mimicking a human retina.
