Sweat holds great promise for noninvasive testing - health technology short science news

Scientists and clinicians search for biosensors that accurately reflect metabolite concentrations and effects of drugs in the blood.

It turns out that measurements in sweat hold great promise for such continuous, noninvasive testing. They give very similar results as measuring in blood, and the secretion of sweat can be controlled and stimulated, even if a person is resting and cool.

Sweat sensors are under development, and the first sensors, the size of a Band-Aid that can be applied on the skin, are likely to become available soon.
