MicroSweat: A Wearable Microfluidic Patch for Noninvasive and Reliable Sweat Collection Enables Human Stress Monitoring (Adv. Sci. 7/2023)

MicroSweat for Human Stress Monitoring A wearable, self-power, skin-interfaced, and scalable surfactant-free microfluidic patch (MicroSweat) was developed and successfully used for reliable sweat collection and Chrono sampling of the human sweat. MicroSweat facilitates measuring the sweat cortisol stress biomarker in different body locations, with the most predictive cortisol concentration detectable in the armpits. This study provides valuable sweat cortisol data as an essential basis for the detection of human stress levels. More details can be found in article number 2204171 by Jaideep S.
