Graphene-coated smart contact lenses could protect eyes from EM radiation and dehydration
Researchers at Seoul National University, Graphene Square and Interojo have shown that graphene-coated contact lenses could protect eyes from electromagnetic radiation and dehydration and be used in various healthcare and wearable technologies.
The researchers began by synthesizing a graphene layer on a copper foil using CVD. They then transferred the carbon sheet onto the surface of a contact lens with the help of a polymer layer after etching the copper. "Thanks to its outstanding flexibility, graphene can be coated on the convex lens surface and conform to it," explains the team.
