Abstract Stress affects cognition, behavior, and physiology, leading to lasting physical mental illness. The ability detect measure stress, however, is poor. Increased circulating cortisol during stress mirrored by release from sweat glands, providing an opportunity use it as external biomarker for monitoring internal emotional state. Despite the attempts at using wearable sensors cortisol, there a lack of reliable collection devices that preserve concentration integrity biomolecules...
Blood lactate concentration is an established circulating biomarker for measuring muscle acidity and can be evaluated monitoring endurance, training routines, or athletic performance. Sweat alternative biofluid that may serve similar purposes offers the advantage of noninvasive collection continuous monitoring. The relationship between blood dynamic sweat biochemistry wearable engineering applications in physiological fitness remains poorly defined. Here, we developed a microfluidic band...
