Scientists have developed the first ultra-thin, flexible device that sticks to skin like a rub-on tattoo and can detect a person’s glucose levels. The sensor, reported in a proof-of-concept study in the ACS journal Analytical Chemistry, has the potential to eliminate finger-pricking for many people with diabetes.
The researchers made a wearable, non-irritating platform that can detect glucose in the fluid just under the skin based on integrating glucose extraction and electrochemical biosensing. Preliminary testing on seven healthy volunteers showed it was able to accurately determine glucose levels. The researchers conclude that the device could potentially be used for diabetes management and for other conditions such as kidney disease.
