Dr. Takaya Sato is currently the vice president of 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 Ph. D. in polymer chemistry from Kyoto University in 1992 under direction of Professor Takeaki Miyamoto. After acquiring a degree, he has been engaged in the development of functional polymer materials such as micro-particles for cosmetics, gel materials for microbial carriers, solid polymer electrolytes for lithium ion batteries and some novel ionic liquids in Nisshinbo Holdings. Inc. In 2003, it was the first time in the world to commercialize an electric double layer capacitor using an ionic liquid as an electrolyte. After moving to the Tsuruoka College as a professor in 2004, he is continuing the development of ionic liquids and related polymer materials and are vigorously conducting research to apply them to electrochemical devices and low friction materials.
