Researchers at the University of Minnesota, US, have 3D-printed an array of light receptors on a hemispherical surface, which can be used to create a bionic eye to assist blind and partially sighted people in seeing better.
The research was funded by the National Institute of Biomedical Imaging and Bioengineering of the National Institutes of Health, The Boeing and the Minnesota Discovery, Research, and InnoVation Economy (MnDRIVE) Initiative through the State of Minnesota.
