Sensor breakthrough brings us closer to blood glucose monitoring on wearables
https://www.digitaltrends.com/mobile/non-invasive-blood-glucose-measurement-wearables-breakthrough/?ampBlood glucose monitoring is touted to be the next big breakthrough for wearable devices like the Apple Watch. However, the hardware is yet to be seen on a commercially available, mass-market device. That might change soon.
A team from Georgia’s Kennesaw State University claims to have developed a noninvasive system of blood glucose level measurement, thanks to a device called GlucoCheck. It follows the same fundamental approach as the oxygen-level analysis sensor on smartwatches like the Apple Watch Series 8 and Samsung Galaxy Watch 5.
Team lead Maria Valero, an assistant professor at the institution’s College of Computing and Software Engineering (CCSE), notes that the device delivers 90% accuracy in analyzing glucose concentration in blood samples. The biosensor works in tandem with a phone application, but the team is already at work on integrating Amazon’s Alexa virtual assistant.
GlucoCheck shines light across the human skin, and then a camera captures the view from the other side. The goal is to study the varying level of light absorption by blood flowing in the vessels to determine the glucose concentration.
