Electronics on anything: How thin film electronics can instrument the world

Ioannis KymissisProfessorColumbia 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 the same size scale as the systems they interact with, and the ability to integrate electronic materials on a range of substrates including electronically active and flexible materials. Our group has been working on the hybrid integration of organic
semiconductors and SLS laser-recrystallized silicon with active substrates to implement sensing, display, and mechanical actuation
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.
Using this capability we have demonstrated the electronic implementation of all five senses as well a new approaches to mechanical actuation in polymer materials and driving LEDs in display
engines. In particular, I'll show how thin film transistors can be integrated with other active materials to build monolithically integrated microphones and pressure sensors, flexible sheet scanners, mass-based chemical sensors, high power light engines, and segmented polymer actuators. It is our hope that these devices will form some of the building blocks for future electronic systems and interface paradigms with application in a range of technological and healthcare areas.
Ioannis (John) Kymissis is an electrical engineer teaching at Columbia University. His area of specialization is solid state electronics and device fabrication. His research focuses on thin film devices and systems, especially focusing on optoelectronic and sensing devices based on organic and recrystallized inorganic thin film materials. Current areas of research include investigations into device performance, system integration, fabrication, packaging, and device
John 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 several other foundation, corporate, and best paper awards. He is the editor in chief of the Journal of the Society for Information Display, and is the technical program committee chair for the 2012 Device Research Conference.
