CBE Colloquia - Soft Intelligent Bioelectronics and In-Body Networks for Connected Healthcare and Human-Machine Interfaces

Conventional biomedical diagnostic and therapeutic devices remain fundamentally constrained by the mechanical mismatch between rigid electronic components and soft, curvilinear biological tissues. This mechanical disparity often induces interfacial motion artifacts, tissue irritation, and severe signal degradation during long-term monitoring. To overcome these operational bottlenecks, Dr. Yeo will present recent paradigm shifts from his research group at Georgia Tech in soft, intelligent bioelectronics and in-body networks designed for continuous physiological tracking and intuitive human-machine interfaces. In this talk, Dr. Yeo will detail the underlying scientific principles of ultra-thin, low-modulus nanomembrane biosensors that his team has engineered to conformally integrate with native biological substrates in both wearable and implantable formats. He will highlight key methodologies, including multiscale materials design, high-throughput printing-based nanomanufacturing, and robust hybrid hard–soft packaging strategies that maintain structural integrity and electrical functionality under complex, dynamic strain profiles. Drawing from their recent in vitro and in vivo evaluations, Dr. Yeo will showcase the exceptional signal fidelity, biostability, and real-time analytical capabilities of these integrated systems. Specifically, he will illustrate their deployment in high-precision, continuous electrophysiological monitoring, quantitative biomarker detection, closed-loop targeted therapeutics, and adaptive human-machine control systems. Dr. Yeo will conclude with a discussion on current translational barriers, scalable manufacturing pathways, and his vision for the future trajectory of smart, connected bioelectronics in enabling personalized, preventive healthcare systems.
