TxACE Distinguished Lecturer
A characteristic feature of modern silicon integrated circuit technology is its ability to last forever, in almost any practical sense. Recent work demonstrates that carefully selected sets of materials and device designs enable a class of silicon electronics that has the opposite behavior -- it physically disappears in water or biofluids, in a controlled manner, at programmed times. This talk summarizes recent work on this type of ‘transient’ electronics technology, ranging from basic studies of dissolution of the key materials, to development of components and systems with radio frequency operation, to invention of schemes for externally ‘triggering’ transient behavior. Applications ranging from resorbable biomedical implants, to ‘green’ RFID tags and hardware security systems provide examples of envisioned practical utility.
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. He is also Director of the Seitz Materials Research Laboratory.
Rogers’ research includes fundamental and applied aspects of materials and patterning techniques for unusual electronic and photonic devices, with an emphasis on bio-integrated and bio-inspired systems. He has published more than 400 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 AAAS, and he is a member of the National Academy of Engineering. His research has been recognized with many awards, including a MacArthur Fellowship in 2009, the Lemelson-MIT Prize in 2011, and the Mid-Career Researcher Award (MRS), the Robert Henry Thurston Award (ASME), and the Smithsonian Ingenuity Award for the Physical Sciences, in 2013.
