Cheap, noninvasive patch monitors glucose

UCSD’s Joe Wang‘s needless adhesive glucose monitor has begun a phase I clinical trial.  The small patch measures insulin levels through sweat on the skin, eliminating the need for a skin prick.  The paper – tattoo is printed with two integrated electrodes that apply a small amount of electrical current.  Glucose molecules residing below the skin are forced to rise to the surface, allowing blood sugar to be measured.

Through its SENSOR study,  the team s testing the tattoo-like sensor’s accuracy, compared to a traditional glucometer. The  trial is enrolling 50 adults, ages 18 to 75, with type 1 or 2 diabetes, or diabetes due to other causes. Participants wear a sensor while fasting, and up to 2 hours after eating.

The goal is a cheap, noninvasive, discreet, user friendly glucose monitor that provides continuous measurement.  The sensor currently provides only one readout.
