Soft Electronics for the Human Body
John A Rogers
Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering and Medicine, Northwestern University
Biological systems are mechanically soft, with complex, 3D curvilinear shapes; modern electronic devices are rigid, with simple, 2D layouts. Eliminating this profound mismatch in physical properties will create vast opportunities in man-made systems that can intimately integrate with the human body, for diagnostic, therapeutic or surgical function with important, unique capabilities in fitness/wellness, sports performance and clinical healthcare. Over the last decade, a convergence of new concepts in materials science, mechanical engineering, electrical engineering and advanced manufacturing has led to the emergence of diverse, novel classes of 'biocompatible' electronic systems with physical properties matched to soft biological tissues. This talk describes the key ideas and presents some of the most recent device examples in skin-interfaced technologies, including wireless, battery-free electronic 'tattoos' that can continuously monitor all vital signs at clinical grade precision, with applications in neonatal and pediatric intensive care; and microfluidic/electronic platforms that can capture, manipulate and perform biomarker analysis on microliter volumes of sweat, with applications in sports and health diagnostics.
John A. Rogers is the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering and Medicine at Northwestern University, with affiliate appointments in Mechanical Engineering, Electrical and Computer Engineering and Chemistry, where he is also Director of the recently endowed Center for Bio-Integrated Electronics. He has published more than 700 papers, is a co-inventor on more than 100 patents and he has co-founded several successful technology companies. His research has been recognized by many awards, including a MacArthur Fellowship (2009), the Lemelson-MIT Prize (2011), the Smithsonian Award for American Ingenuity in the Physical Sciences (2013) and most recently the MRS Medal (2018) and the Benjamin Franklin Medal (2019). He is a member of the National Academy of Engineering, the National Academy of Sciences, the National Academy of Inventors and the American Academy of Arts and Sciences.
