Professor Sei Kwang Hahn’s team at POSTECH develops wireless smart contact lenses for diagnosis and treatment of diabetes
Diabetes is called an incurable disease because once it develops, it does not disappear regardless of treatment in modern medicine. Having diabetes means a life-long obligation of insulin shots and monitoring of blood glucose levels. But what if you could control the secretion of insulin just by wearing contact lenses?
Recently, a research team at POSTECH developed wirelessly driven ‘smart contact lens’ technology that can detect diabetes and further treat diabetic retinopathy just by wearing them.
Professor Sei Kwang Hahn and graduate students Do Hee Keum and Su-Kyoung Kim of POSTECH’s Department of Materials Science and Engineering, and Professor Jae-Yoon Sim and graduate student Jahyun Koo of Department of Electronics and Electrical Engineering have developed a wireless powered smart contact lens that can diagnose and treat diabetes by controlling drug delivery with electrical signals. The findings were recently published in Science Advances, a world-renowned journal. The smart contact lenses developed by the research team are made of biocompatible polymers and integrate biosensors and drug delivery and data communication systems.
The research team verified that the glucose level in tears of diabetic rabbits analyzed by smart contact lenses matched their blood glucose level using a conventional glucose sensor that utilize drawn blood. The team additionally confirmed that the drugs encased in smart contact lenses could treat diabetic retinopathy.
Recently, by applying the platform technology of these smart contact lenses, a research has been conducted to expand the scope of electroceuticals that use electrical stimulations to treat brain disorders such as Alzheimer’s and Parkinson’s diseases, and mental illnesses including depression.
The research team expects this development of self-controlled therapeutic smart contact lenses with real-time biometric analysis to be quickly applied to wearable healthcare industries.
Professor Sei Kwang Han who led the research stated, “Despite the full-fledged research and development of wearable devices from global companies, the commercialization of wireless-powered medical devices for diagnosis and treatment of diabetes and retinopathy is insufficient.” He added, “We expect that this research will greatly contribute to the advancement of related industries by being the first in developing wireless-powered smart contact lenses equipped with drug delivery system for diagnosis and treatment of diabetes, and treatment of retinopathy.”
