Researchers develop soft, microfluidic patch for sweat analysis

Low-cost wearable electronic device collects and analyzes sweat for health monitoring

A Northwestern University research team has developed a first-of-its-kind soft, flexible microfluidic device that easily adheres to the skin and measures the wearer’s sweat to show how his or her body is responding to exercise.

A little larger than a quarter and about the same thickness, the simple, low-cost device analyzes key biomarkers to help a person decide quickly if any adjustments, such as drinking more water or replenishing electrolytes, need to be made or if something is medically awry. 

Designed for one-time use of a few hours, the device, placed directly on the skin of the forearm or back, even detects the presence of a biomarker for cystic fibrosis. In the future, it may be more broadly used for disease diagnosis.

A new sweat-monitoring device measures four chemical components in sweat, a "rich, chemical broth," explains John A. Rogers. - Nov. 23, 2016

Designed and manufactured by the Rogers Lab at Northwestern University, the soft, flexible bio-integrated lab is the next generation of wearable technology and has been featured in the Modern Museum of Art (MoMA) in New York. - Jan. 9, 2018
