Smart contact lenses with sensor technology that monitor blood glucose have been developed by researchers at Purdue University in Indiana. The new technology, called the GlucoWatch System, is a wearable device that uses an accelerometer and gyroscope to measure how much sugar your body has absorbed from food. To address the problem, Purdue researchers used a process called "interfacial debonding" to separate thin-film electronics from their wafer substrate and print them on to another material. However, there are still questions over how reliable tears are at reflecting blood glucose levels.
