Prototype smart ring cracks the holy grail of non-invasive blood sugar measurement
9to5Mac • • health
Key Points:
- Engineers at the University of California, San Diego have developed a prototype smart ring capable of non-invasive blood sugar measurement by analyzing sweat, marking a significant advancement in health wearables.
- Unlike current smart rings that rely on biophysical sensors similar to the Apple Watch, this ring tracks chemical biomarkers such as glucose, ketones, vitamin C, uric acid, lactate, and alcohol concentrations through finger sweat.
- The ring continuously monitors up to four biochemical markers simultaneously, offering potential benefits for people with Type 1 diabetes by aiding in optimal insulin dosing.
- Testing demonstrated that the prototype's accuracy in glucose monitoring is comparable to invasive continuous glucose monitors and blood draws.
- Although the prototype is bulky with a limited 12-hour battery life, future commercial versions could improve on these aspects, potentially revolutionizing wearable health technology.
