Skin-interfaced wearable biosensors

Wearable sweat biosensors have the potential to provide non-invasive molecular analysis toward predictive analytics and treatment. In this talk, I will introduce our efforts in developing wearable biosensors for non-invasive molecular analysis. Such wearables can autonomously access body fluids (e.g., human sweat) across the activities and continuously measure a broad spectrum of analytes including metabolites, nutrients, hormones, and proteins. Laser engraving and inkjet printing are used to manufacture high-performance nanobiosensors at large scale and low cost. The clinical value of our wearable systems is evaluated through various human trials toward precision nutrition, stress/mental health assessment, and chronic disease management.
