Abstract: When mounted on the skin, advanced sensors, circuits, radios and power supply systems have the potential to provide clinical-quality health monitoring capabilities for continuous use, outside of traditional hospital settings or laboratory facilities.  The most well-developed component technologies are, however, currently available only in hard, planar formats.  As a result, existing options in system design are unable to effectively accommodate integration with the soft, textured, curvilinear and time-dynamic surfaces of the skin.  Here, we describe experimental and theoretical approaches for using soft materials, ultrathin micro/nanostructures, and controlled processes of mechanical buckling to achieve ultralow modulus, highly stretchable systems of state-of-the-art semiconductor devices.  The result is a skin-like technology with measurement fidelity that can match that of large-scale tools currently used in clinical medicine.  This talk reviews these and other systems, as well as opportunities in further technology enhancements, with an emphasis on strategies for mitigating body-induced RF absorption, motion-induced artifacts and frequency crosstalk in devices powered by far field RF energy transfer.
About the Speaker: Professor John A. Rogers obtained BA and BS degrees in chemistry and in physics from the University of Texas, Austin, in 1989.  From MIT, he received SM degrees in physics and in chemistry in 1992 and the PhD degree in physical chemistry in 1995.  From 1995 to 1997, Rogers was a Junior Fellow in the Harvard University Society of Fellows.  He joined Bell Laboratories as a Member of Technical Staff in the Condensed Matter Physics Research Department in 1997, and served as Director of this department from the end of 2000 to 2002.  He is currently Swanlund Chair Professor at University of Illinois at Urbana/Champaign, with a primary appointment in the Department of Materials Science and Engineering, and joint appointments in several other departments, including Chemistry.  He is Director of the Seitz Materials Research Laboratory.
Rogers’ research includes fundamental and applied aspects of materials for unusual electronic and photonic devices, with an emphasis on bio-integrated and bio-inspired systems.  He has published more than 450 papers and is inventor on over 80 patents, more than 50 of which are licensed or in active use.  Rogers is a Fellow of the IEEE, APS, MRS and the AAAS, and he is a member of the National Academy of Engineering and the American Academy of Arts and Sciences.  His research has been recognized with many awards, including a MacArthur Fellowship in 2009, the Lemelson-MIT Prize in 2011, the MRS Mid-Career Researcher Award and the Robert Henry Thurston Award (American Society of Mechanical Engineers) in 2013, and the 2013 Smithsonian Award for Ingenuity in the Physical Sciences.
