Professor Takaya Sato is currently the vice president of the National Institute of Technology, Tsuruoka College, Japan, and professor of polymer chemistry. He studied polymer and fiber chemistry at Shinshu University and Kyoto University. He received his PhD in Polymer Chemistry from Kyoto University in 1992 under the direction of Professor Takeaki Miyamoto. After acquiring a degree, he was engaged in the development of func-

tional polymer materials such as microparticles for cosmetics, gel materials for microbial carriers, solid polymer electrolytes for lithium ion batteries, and novel ionic liquids in Nisshinbo Holdings, Inc. 2003 was the first time that an electric double layer capacitor using an ionic liquid as an electrolyte was commercialized. After moving to Tsuruoka College as a professor in 2004, Professor Miyamoto continues to develop ionic liquids and related polymer materials and is vigorously conducting research to apply them to electrochemical devices and low friction materials.
