Contact Lenses May Soon Monitor Glucose Levels
Diabetes patients may soon be able to monitor their blood sugar with contact lenses – spelling an end to painful jabs – thanks to scientists who have developed a transparent sensor. The sensor developed by the researchers from Oregon State University (OSU) in the US, uses a nanostructured transistor that can detect subtle glucose changes in physiological buffer solutions, such as the tear fluid in eyes. Researchers in the OSU said the nanostructured transistor is specifically an amorphous indium gallium oxide field effect transistor (IGZO FET). The sensors they fabricated…
