"The researchers used a custom-built 3D printer to construct their bionic eye prototype. First, they printed a base of silver particles on the inside of a hemispherical glass dome. Next, they used semiconducting polymer materials to print photodiodes, devices that convert light into electric signals, on top of the silver base.
The entire process took about an hour, after which the team had a bionic eye that could convert light into electricity with 25 percent efficiency (safe to say that’s less than our natural eyes can do, since they can detect a single photon)."
