Flexible and stretchable electronics are attracting much attention because of the variety of potential applications from flexible e-papers though wearable healthcare devices. Among various kinds of electronic materials, carbon nanotube thin films have advantages in flexibility, stretchability, and performance because of the excellent electronic and mechanical properties. Low cost manufacturing of flexible devices is also possible with good processability of carbon nanotube films. Their optical transparency is also attractive for optoelectronic device applications. In my presentation, I will talk about our recent works on carbon nanotube-based flexible TFTs and ICs [1-4], high-speed printing technique [5], and simple micro-pattering technique of CNT films and its application for capacitive touch screens [6].

CV: Ohno

Yutaka Ohno is an Associate Professor of Department of Quantum Engineering, Nagoya University. He received the B.E., M.E., and Ph.D. degrees from Nagoya University in 1995, 1997, and 2000, respectively. His Ph. D dissertation investigated resonant-tunneling phenomena and the optoelectronic-functional devices in 2-D and 0-D semiconductors heterostructures.

He worked for one year as a Research Scientist of Japan Society for the Promotion of Science when he was a graduate student. He became a research associate in 2000, an assistant professor in 2002, and an associate professor in 2008 of the Department of Quantum Engineering, Nagoya University. He was also a Research Scientist of Japan Science and Technology Agency from 2004 to 2007, and a visiting professor of Aalto University, Finland from 2012 to 2013.

He worked on GaN HEMT devices from 2000 to 2004. Currently, he is involved in the research on carbon nanotube electronics, particularly, fabrication and characterization of flexible devices based on carbon nanotube thin films for healthcare electronics applications.
