Introduction to Micromechatronics

In these several years, piezoelectric materials have bocome key components in smart actuator/sensor systems such as precision positioners, miniature ultrasonic motors and adaptive mechanical dampers. This paper reviews recent developments of piezoelectric and related ceramic actuators with particular focus on the improvement of actuator materials, device designs and applications.

Biographical Sketch:
Kenji Uchino, one of the pioneers in piezoelectric actuators, is the Director of International Center for Actuators and Transducers and Professor of Electrical Engineering at The Pennsylvania State University. After being awarded his Ph. D. degree from Tokyo Institute of Technology, Japan, Uchino became Research Associate in physical electronics department at this university. Then, he joined the Sophia University, Japan as an Associate Professor in physics in 1985. He then moved to Penn State in 1991. He was also involved with Space Shuttle Utilizing Committee in NASDA, Japan during 1986-88, and was the Vice President of NF Electronic Instruments, USA, during 1992-94. He has been consulting more than 60 Japanese, US and European industries to commercialize the piezoelectric actuators. He is the Chairman of Smart Actuator/Sensor Study Committee partly sponsored by the Japanese Government, MITI. He is also the executive associate editor for Journal of Advanced Performance Materials (Kluwer Academic), the associate editor of J. Intelligent Materials Systems and Structures (Technomic) and an editorial board member of Ferroelectrics (Gordon and Breach), Sensors and Materials (Myu), Smart Materials and Structures (IOP), and J. Electroceramics (Kluwer Academic). His research interests are in solid state physics - especially dielectrics, ferroelectrics and piezoelectrics, including basic research on materials, device designing and fabrication processes, as well as development of solid state actuators for precision positioners, ultrasonic motors, etc. He has authored 350 papers, 30 books and 19 patents in the ceramic actuator area. He is a Fellow of American Ceremic Society from 1997, and also is a recipient of the Outstanding Research Award from Penn State Engineering Society (1996), Academic Scholarship from Nissan Motors Scientific Foundation (1990), Best Movie Memorial Award at Japan Scientific Movie Festival (1989), and the Best Paper Award from Japanese Society of Oil/Air Pressure Control (1987).
