Sweat carries a rich mix of biomarkers that advanced wearables can now track in real time. New AI-powered patches analyze biochemical patterns to detect disease risks, medication levels, or stress responses. Researchers are building ultra-sensitive microfluidic devices to read glucose, cortisol, and more—without needles or blood draws. The tech is still emerging, but its potential is huge.
