UA Researchers Go the Distance for Fluid Analysis Via Sweat

A team including UA biomedical engineer Marv Slepian has developed a wearable sensor that measures biomarkers in sweat to reveal information about the body’s chemistry, fluid status and response to exercise.

While participating in last year's El Tour de Tucson, a competitive long-distance bicycle race, more than a dozen volunteers were simultaneously participating in and conducting a real-world scientific study, one that involved a diminutive device that rapidly and painlessly analyzes body chemistry from sweat.

Among the volunteers were faculty and students at the University of Arizona and University of Illinois who helped develop a first-of-its-kind soft, stretchable, wearable microfluidic sweat sensor. The device is applied and directly adheres to the skin and measures biomarkers in the wearer's sweat to reveal information regarding internal chemistries, loss of electrolytes, fluid status and the overall body's response to exercise. 

We wanted to rapidly and painlessly obtain information, without needles, about the body's internal milieu," said Dr. Marvin J. Slepian, director of the Arizona Center for Accelerated Biomedical Innovation, or ACABI, at the UA Health Sciences.
