Gyoujin Cho received a Ph.D. degree from the University of Oklahoma, Norman, in 1995. In 1996, he joined the faculty of the Department of Chemical Engineering, Sunchon National University, Korea, and currently he is a faculty member in the Department of Printed Electronics Engineering, BK21 Program at Sunchon National University. Up to present, he demonstrated the fully printed NFC cyclic volammetry tag and fully R2R gravure printed TFT-active matrix based flexible e-paper for the first time in the world.

Institute: Department of Printed Electronics Engineering, Sunchon National University, was launched in 2008 through the World Class University Program in Korea and leads the world in the field of all R2R gravure printed TFT-based flexible electronic devices such as tactile sensor arrays, NFC sensor tags, and signage.
