Measuring Sweat Glucose of Patients With Diabetes

This pilot clinical trial will explore the accuracy and acceptability of a non-invasive, wearable glucose sensor in patients living with DM. This study will compare needleless glucose sensor readings from sweat with glucometer measurements from patients with any type of diabetes at fasting, and after a meal.

There is an unmet need for a non-invasive glucose monitoring device. UCSD nanoengineers developed a flexible, ultra-thin sensor adherent to the skin, similar to a temporary tattoo. Sweat glucose correlates with blood glucose. This proposed study would be the first to examine this needle-free glucose sensor to measure glucose in endogenous sweat in individuals with DM, and would serve as the basis for future development of a continuous, non-invasive sensor. The investigators hypothesize that compared with a glucometer, a tattoo sensor can accurately measure sweat glucose in patients with DM.
