Dr. Ioannis (John) Kymissis of Columbia University

Silicon electronics have revolutionized the processing and handling of information. The high temperatures required to create crystalline silicon devices, however, has limited the application of crystalline silicon to sensing systems that work in a small and mechanically rigid form factor. The development of inorganic and organic thin film electronics has launched a second revolution in electronics, granting the ability to process electronically active materials at low temperatures. This has allowed for two exciting opportunities: the ability to build electronic devices on large format substrates on the same size scale as the systems they interact with, and the ability to integrate electronic materials on a range of substrates including the back-end of CMOS integrated circuits, electronically active substrates, and flexible materials.

Our group has been working on the hybrid integration of organic semiconductors, thin film piezoelectrics, and laser-recrystallized materials with active substrates to implement a range of new functionalities. In this presentation, I'll show how thin film electronics and the hybrid integration enabled by new semiconductor systems and process options allows for active and spatially localized control of systems that are typically used in a single element format. Devices we have developed include large area and miniature microphones, pressure sensors, active matrix flexible electrostrictive actuators, miniature spectrometers, and active matrix micro-LED displays. These approaches unlock new applications in healthcare, sensing, displays, soft and highly instrumented robotics, transportation, and communications.

Biography:

Ioannis (John) Kymissis graduated with his SB, M.Eng., and Ph.D. degrees from MIT. His M.Eng. thesis was performed as a co-op at the IBM TJ Watson Research Lab on organic thin film transistors, and his Ph.D. was obtained in the Microsystems Technology Lab at MIT working on field emission displays. After graduation he spent three years as a post-doc in MIT's Laboratory for Organic Optics and Electronics working on a variety of organic electronic devices and as a consulting engineer for QDVision. He joined the faculty at Columbia University in Electrical Engineering in 2006 as an assistant professor. John has won a number of awards for his work, including the NSF CAREER award, the IEEE EDS Paul Rappaport award, the Vodaphone Americas Foundation Wireless Innovation Award, the MIT Clean Energy Prize, and a Verizon Powerful Answers award. He recently served a term as the editor in chief of the Journal of the Society for Information Display, and was the general chair for the 2014 Device Research Conference.
