Biography

Dr. Minoru Taya has been a Professor of Mechanical Engineering, and Adjunct Professor of Materials Science and Engineering at the University of Washington since 1986. He received a Bachelor of Engineering in 1968 from the University of Tokyo, Japan; Master of Science in Civil Engineering in 1973 and Doctor of Philosophy in Theoretical Applied Mechanics in 1977, both from Northwestern University. He taught at the University of Delaware as an Assistant and Associate Professor from 1978-1985. He has had visiting appointments at the University of Oxford, U.K., Risø National Laboratory, Denmark, University of Tokyo, and Institute of Space and Aeronautical Science, Japan. During 1989-1991 he was Professor of Materials Systems, Department of Materials Processing, Tohoku University, Japan, where he supervised a number of research projects on processing composites.

Dr. Taya is currently running a Center for Intelligent Materials and Systems (CIMS) as Director, where he is involved in supervising a number of projects related to intelligent materials and systems. The intelligent materials that he has been studying are shape memory alloys(SMA), ferromagnetic SMA(FSMA), piezo-composites, electro- and photo-active polymers, and designed actuators based on these materials, including compact ferromagnetic SMA spring actuators, which provides a large stroke and reasonably large force at very high actuation speed. The FSMA actuators are for use in unmanned aircrafts and unmanned ground rover, as well as robotic arms. The electroactive polymers (EAPs) that Dr. Taya's group has been studying include hydrogels such as Nafion and Flemion, and electrochromic polymers . These EAPs are the key materials for fish fin actuators, smart antenna and smart window technology. In addition, Dr. Taya has been working on design, processing of Thermal Interface Materials(TIMs) that have high thermal conductivity, thus for use an interface material between heat dissipating chips and pumped diodes and heat sink/spreader. Dr. Taya's group is also involved in designing a temperature sensor with high special resolution. The details of CIMS activities are given at http://depts.washington.edu/cims/

Dr. Taya's research interest lies two major area, (1) electronic packaging and composites, and (2) smart materials. In the former, he is working on designing, processing, characterizing a set of new electronic composites with emphasis on high thermal conductivity materials while the materials in the latter area are piezoelectric composites, shape memory alloys and polymer gels which exhibit small to larger strain in this order under applied thermal and electromagnetic field. The smart materials are the key materials for high performance actuators, ranging from MEMS to artificial muscles.

Dr. Taya serves as Associate Editor for Materials Science and Engineering-A, and ASME Journal of Applied Mechanics, and is currently chair of the Electronic Materials Committee of ASME Materials Division. Dr. Taya is Fellow of ASME, and American Academy of Mechanics, and International Editorial Board member of Advanced Composite Materials.

As for non-academic activities, Dr. Taya enjoys outdoor activities such as fly fishing for trout and salmon, jogging, golfing and tennis.
