Researchers’ device tracks biomarkers in sweat, may indicate flare-ups — ScienceDaily

University of Texas at Dallas researchers have designed a wearable device that monitors sweat for biomarkers that could signal flare-ups of inflammatory bowel disease (IBD).

A team of bioengineers demonstrated the wristwatch-like device in a proof-of-concept study funded by the Crohn’s & Colitis Foundation and published online July 28 and in the October print edition of the foundation’s journal, Inflammatory Bowel Diseases.

A sensor in the device detects and quantifies the presence of two key biomarkers associated with inflammatory bowel disease: interleukin-1β and C-reactive protein (CRP). The study is the first to establish that CRP is present in human sweat and the first to show that the two biomarkers can be detected in sweat.

Dr. Shalini Prasad, department head and professor of bioengineering in the Erik Jonsson School of Engineering and Computer Science and the study’s principal investigator, said the technology could provide a warning but not a diagnosis
