Wearable sensors which measure levels of molecules in a patient’s sweat are now able to provide real-time information on an individual’s physiology and health.

Sweat contains much information in the form of metabolites such as glucose, and electrolytes such as sodium, which could be used to help diagnose diseases or identify drug use.

The developers of the technology believe that besides monitoring a person’s health, the platform could be useful in clinical studies by identifying biomarkers in sweat.
