Transparent, stretchable lens sensor for diabetes, glaucoma detection

UNIST professors Jang-Ung Park, Chang Young Lee and Franklin Bien, and KNU professors Hong Kyun Kim and Kwi-Hyun Bae, have developed a contact lens sensor to monitor biomarkers for intraocular pressure, diabetes mellitus, and other health conditions. Several attempts have been  made to monitor diabetes via glucose in tears.  The challenge has been poor wearability, as the electrodes used in existing smart contact lenses are opaque, obscuring  one’s view.  Many wearers also complained of significant discomfort from the lens-shaped firm plastic material. The research team addressed this by developing a sensor based on transparent, stretchable, flexible materials  graphene sheets and metal nanowires. This allowed the creation of lenses comfortable and accurate enough for eventual self-monitoring of glucose levels and eye pressure. Patients can transmit their health information through an embedded wireless antenna in the leans, allowing real-time monitoring  The system uses  the wireless antenna to read sensor information, eliminating the need for a separate power source.
