There are many contact lenses in the market that after wearing in eye, one may feel comfortable, but he/she has to face a slight problem when placing the lenses on our eyeballs. Recently a group of researchers at several institutions, including two research arms of Samsung, has built soft, transparent contact lens displays with nanomaterials that could display information to the wearer and provide continuous medical monitoring.
By putting silver nanowires between graphene layers, researchers created transparent conductors that can drive LEDs while remaining flexible enough to sit on a contact lens. The lenses are so soft that even rabbits can wear them and can have a view perfectly for five hours without strain.
Jang-Ung Park, a chemical engineer at the Ulsan National Institute of Science and Technology and the leader of the group wants to make such contact lenses that would have all the functions of a wearable computer but remain transparent and soft. He said, “Our goal is to make a wearable contact-lens display that can do all the things Google Glass can do.”
