Scientists have developed a new smart contact lens with built-in wireless sensors that may help diagnose diabetes, glaucoma and other health conditions.
Researchers from Ulsan National Institute of Science and Technology (UNIST) in South Korea, in collaboration with researchers from Kyungpook National University, have developed the lens, which could assist with monitoring biomarkers for intraocular pressure, diabetes mellitus and other health conditions.
The new lens’s sensor is based on transparent and flexible materials and the lens itself is made with electrodes comprised of highly stretchable and transparent graphene sheets and metal nanowires.
With the sensor, patients with diabetes and glaucoma could in the future be able to self-monitor their blood glucose levels and eye pressure. Patients can transmit their health information in real-time using the embedded wireless antenna in the lens. The wireless antenna also does not require a separate power source like a battery.
The intraocular pressure measurement is achieved by using an electrically non-conductive layer characterized by polarity that divides both positive and negative charges called a dielectric layer.
