A University of Minnesota research team has 3D-printed an array of light receptors on a hemispherical surface, in a first step toward creating a “bionic eye” that could someday help blind people see or sighted people see better. Using their custom-built 3D printer, the researchers started with a base ink of silver particles. The ink, … Continue reading 3D-Printed Polymer Photodetectors on Curved Surface a “Bionic Eye”
