3D-Printed Material Could Lead to Artificial Retinas

Aug-30-18 A 3D-printed material able to convert light to electricity could one day be used to create a bionic eye.

A team from the University of Minnesota created the material by 3D-printing lines of conductive ink onto a hemispherical glass dome similar in shape to the back of the human eye. They then added a layer of semiconducting polymer, resulting in photodiodes able to convert light into an electric current. The system is 25 percent effective, and the team plans to improve that efficiency as well as print the system on a soft material that could replace the retina.
