Asian Research Network develops CNT touch sensors, electronic ink

February 28, 2012 – JCN Newswire — Hanyang University of Korea, RIKEN of Japan, and other Asian universities and research institutes launched the Asian Research Network (ARN) to strengthen research and educational cooperation across Asia. ARN members have produced transparent touch sensors using carbon nanotubes (CNT), and inks that can print electronic circuits that change color under heat or UV exposure.

Choi Eunsuk and colleagues made a transparent touch sensor using optically transparent and electrically conductive CNT thin films. Applications include flexible electronic interfaces such as e-paper or television displays. Access the article: Choi Eunsuk, Kim Jinoh, et al. "Fabrication of a flexible and transparent touch sensor using single-walled carbon nanotube thin-films" Journal of Nanoscience and Nanotechnology Vol. 11 7 pp. 5845-5849 (2011). DOI: 10.1166/jnn.2011.4450

Jong-Man Kim and his team developed an ink solution that can repeatedly change color upon exposure to heat or UV radiation. Applications include printed electronic circuits on paper for lightweight, disposable products. Access the article: B. Yoon, D.-Y. Ham, O. Yarimaga, H. An , C. W. Lee, and J.-M. Kim, "Inkjet Printing of Conjugated Polymer Precursors on Paper Substrates for Colorimetric Sensing and Flexible Electrothermochromic Display", Advanced Materials, 2011, 23, 5492-5497. DOI: 10.1002/adma.201103471

Prof. Haiwon Lee, Director of the Institute of Nanoscience and Technology at Hanyang University in South Korea has decades of experience building research alliances across Asia. ARN started as an alliance between two universities, and now incorporates dozens of organizations across Asia: The Chinese Academy of Sciences, Samsung Electronics, Indian Institute of Science Education and Research and National University of Singapore, among others. They collaborate at the Fusion Technology Center in Seoul, South Korea.
