Researchers at Tufts University have developed a flexible electronic sensing patch that can analyze a person's sweat for multiple health markers while being worn.

Sewn into clothing, the device incorporates special sensing threads, electronic components, and wireless connectivity for real-time data acquisition, storage, and processing.

The patch can be used to diagnose acute and chronic health conditions, as well as to monitor athletic performance and workplace safety.

It measures in real time levels of biomarkers found in sweat, like electrolytes, metabolites, pH, and the stress hormone cortisol.

Said Tuft's Trupti Terse-Thakoor, "The markers we can pick up in sweat also correlate well with blood plasma levels which makes it an excellent surrogate diagnostic fluid."
