MEMS Seminar: Wei Gao, “Skin-Interfaced Wearable Biosensors”

Thomas Lord Department of Mechanical Engineering & Materials Science Fall 2024 Seminar Series welcomes Wei Gao, assistant professor of Medical Engineering at the California Institute of Technology, for a talk on “Skin-Interfaced Wearable Biosensors”
ABSTRACT: 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 body fluids (e.g., human sweat) across the activities and continuously measure a broad spectrum of analytes including metabolites, nutrients, hormones, proteins, and drugs. To manufacture these high-performance nanomaterial-based wearable biosensors at a large scale and minimal cost, we employ techniques such as laser engraving, inkjet printing, and 3D printing. The clinical utility of our wearable systems is assessed through a series of human trials, focusing on precision nutrition, stress response and mental health assessment, chronic disease management, fertility management, and drug personalization. I will also delve into our ongoing research into energy harvesting from both the human body and the surrounding environment, with the ultimate aim of achieving battery-free, wireless wearable biosensing. The integration of these wearable technologies has the potential to unlock a wide spectrum of applications, ranging from personalized monitoring and diagnostics to innovative therapeutic solutions.
