Bionic eyes are one step closer to reality, and in the future, they could replace human eyes and help blind people see. Researchers at the University of Minnesota have 3D-printed light receptors onto a prototype for a bionic eyeball.
It’s the first time that light receptors have been successfully printed onto a round surface. The entire 3D printing process only takes an hour.
The bionic "eye" would translate light into images, mimicking the function of a regular eye. UMN's McAlpine research group has already 3D-printed organs and ears. Next, the team wants to print receptors onto soft material, and work on making the eye more efficient.
