This Wearable Patch Uses Sweat To Monitor Blood Glucose Levels

People with diabetes prick their fingers multiple times a day to check their blood glucose levels, and dose themselves daily with injections of insulin. This monitoring is crucial, as rises in sugar levels in the blood can, over time, increase a diabetic patient's risks of developing long-term complications from the disease. But this pricking and injecting can also be painful and tedious, making it harder for people to follow their doctor's orders.
