Functional Nanomaterials and Nanofabrication Processes for Flexible Device Applications
Wearable electronics is becoming a new paradigm for the next generation computing and electronic systems. Leading global companies such as Google, Samsung and Apple are investing huge efforts towards the development and commercialization of wearable and flexible electronic systems. The essential components for the wearable electronic systems are circuit components (eg. transistors and RFIC), display (eg. visual and tactile display), power devices (eg. battery and solar cells), sensors (biosensors and environment sensors), etc. In this talk, I will discuss recent trends and state-of-the-art technology in these component and systems for wearable electronics. Then, I will discuss various chemical and physical sensors that are being developed at our laboratory in KAIST. In specific, I will explain about (1) metal oxide nanowire based flexible gas sensors for toxic gases, (2) metal nanotube based flexible gas sensors for hydrogen gas, (3) photosensitive nanomaterial based flexible UV sensors and (4) metal nanowire / CNT based flexible and stretchable strain sensors for the human motion detection.
Professor Inkyu Park received his Ph.D. (mechanical engineering) at UC Berkeley in 2007. He received a B.S. and M.S. degrees (mechanical engineering) from KAIST in 1998 and UIUC in 2003, respectively. He worked as a research specialist at Berkeley Sensor and Actuator Center (BSAC) in 2007-08 and a visiting researcher at Hewlett Packard Lab in 2005-08. He is currently an associate professor at the department of mechanical engineering @ KAIST. He is an expert in the nanofabrication, sensing devices & systems and mechanical reliability of micro/nano systems. He has published more than 100 articles in international journals and conferences. He also received several awards including Hewlett Packard (HP) Open Innovation Research Award in 2009-2012 and Best Paper Award in IEEE NANO 2010
