Bionic eyes are expected to be stronger than human eyes?

Researchers at the Hong Kong University of Science and Technology described an artificial eye that mimics the structure of the human eye. The bionic eye may achieve a high level of image resolution and is expected to be used in robotics and scientific instruments. The paper was published in Nature on May 20. The researchers proposed a high-density nanowire array of electrochemical eyes and hemispheric retinas to simulate photorepersonal receptors on the human retina.
new study, Fan and colleagues demonstrated a new design: a hemispheric artificial retina containing tightly-lined calcium-titanium photosensitive nanowires that mimic the light receptors of the human eye. By reconstructing the optical patterns projected on the device, the researchers demonstrated the image sensing capabilities of the new bionic device. It was found that the device could "see" objects by reconstructing images observed by artificial eyes (letters "E", "I" and "Y").
, however, the researchers say it is a proof-of-concept device with low resolution. However, they believe the design promises higher resolution than the human eye, as it is possible to increase the density of nanowires to more than 10 times that of the human eye receptor.
