Scientists have developed a soft, flexible contact lens that will allow diabetics to monitor their blood sugar with the blink of an eye. The lens is able to detect a patient’s glucose levels in their tears using built-in wireless sensors. Project leader in Ulsan National Institute of Science and Technology (UNIST) in South Korea, told news service SWNS "This strategy does not require the expensive tools or brittle components currently used in many 'smart' lenses, which can block the user's field of vision and even harm the eye." According to UNIST, the biggest drawback with smart contact lenses is wearability.
So the team developed a special sensor that uses electrodes made of highly stretchable and transparent materials that make the lens easier to wear. Through an embedded wireless antenna in the contact sensor, patients can transmit their health data, allowing real-time monitoring…
