Researchers at the Pohang University of Science and Technology (POSTECH; Pohang, South Korea) have developed smart LED contact lens technology that allows diagnosis of diabetes and treatment of diabetic retinopathy. Professor Sei Kwang Hahn and his research team, including his Ph.D. student, Geon-Hui Lee, invented the smart contact lens and a wearable medical device that can diagnose diabetes and treat diabetic retinopathy. The pair collaborated with a research group led by Zhenan Bao from the Department of Chemical Engineering at Stanford University and David Myung from Stanford Medicine Ophthalmology (Stanford, CA).
The smart contact lens integrates a micro-LED and photodetector that can measure glucose concentration in the conjunctival blood vessels by analyzing the near-infrared light. With this development, they succeeded in diabetic diagnosis. They tested the contact lenses on…
