A team of scientists has developed what they call the Electrochemical Eye (EC-Eye) – bionic eye. Rather than using a two-dimensional image sensor like a camera, the EC-Eye is modeled after a real retina with a concave curve. This surface is studded with an array of tiny light sensors designed to mimic the photoreceptors on a human retina. These sensors are then attached to a bundle of wires made of liquid metal, which act as the optic nerve.
The team tested the EC-Eye (bionic eye) and showed that it can already capture images relatively clearly. It was set up in front of a computer screen displaying large individual letters, and it was able to display them clearly enough to be read.
The technology has the potential to outshine the real thing, by using a denser array of sensors and attaching each sensor to an individual nanowire. Using other materials in different parts of the EC-Eye could bestow users with higher sensitivity to infrared – essentially, night vision.
