Researchers from the University of Beirut have pioneered a non-invasive wearable device that could transform diabetes management. This glove and armband, using electromagnetic wave sensors, offers promising continuous monitoring—though refinements are underway.
For people with diabetes, especially type 1, frequent blood glucose checks are essential—often several times daily. Traditional finger-prick tests can cause discomfort, leading to finger sensitivity issues or, rarely, pulp inflammation.
Detailed in a June 10, 2020, Science Advances study, the EDiamond system—a glove paired with an armband—employs electromagnetic (EM) wave sensors for a truly non-invasive approach, potentially benefiting millions.
Glucose levels alter blood's EM properties. EDiamond sensors emit waves, analyze reflections, and calculate glucose concentrations from wave shifts. Validated on serum and animals, it shows clinical-grade accuracy.
The current prototype remains too bulky for daily wear, and readings need personalization to match individual profiles. The team is advancing sensor miniaturization, envisioning integration into clothing, jewelry, or other wearables.
Key strengths include continuous tracking with real-time data syncing to smartphones, computers, and smartwatches—despite areas for improvement.
