Skin-Interfaced Wearable Biosensors

The rising research interest in personalized medicine promises to revolutionize traditional medical practices. This presents a tremendous opportunity for developing wearable devices 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 sweat across activities and continuously measure a broad spectrum of analytes including metabolites, nutrients, hormones, and drugs. Laser-engraving and inkjet printing are used to manufacture these nanomaterials-based biosensors at large scale and low cost. The clinical value of our wearable systems is evaluated through human studies toward metabolic & nutritional monitoring, disease diagnosis, mental health assessment, and drug personalization. I will also discuss our research progress on energy harvesting from the body fluids and human motion to realize battery-free wireless wearable sensing. These wearable technologies could open the door to a wide range of personalized monitoring, diagnostic, and therapeutic applications.
