    Updating its bestselling predecessor, Ferroelectric Devices, Second Edition assesses the last decade of developments—and setbacks—in the commercialization of ferroelectricity. Field pioneer and esteemed author Uchino provides insight into why this relatively nascent and interdisciplinary process has failed so far without a systematic accumulation of fundamental knowledge regarding materials and device development.

    Filling the informational void, this collection of information reviews state-of-the-art research and development trends reflecting nano and optical technologies, environmental regulation, and alternative energy sources. Like the first edition, which became a standard in the field, this volume provides a general introduction to ferroelectrics with theoretical background. It then addresses practical design and device manufacturing, including recently developed processes and applications. Updating old data with a forecast of future developments, the text analyzes improvements to original ferroelectric devices to aid the design process of new ones.

    The second edition includes new sections on:

    • Pb-free piezoelectrics
    • Size effect on ferroelectricity
    • Electrocaloric devices
    • Micro mass sensor
    • Piezoelectric energy harvesting
    • Light valves and scanners
    • Multi-ferroic devices, including magneto-electric sensors

    Uchino provides a general introduction to the theoretical background of ferroelectric devices, practical materials, device designs, drive/control techniques, and typical applications. He presents frequently asked questions from students, lab demonstrations for practical understanding, and "check point" quizzes and model solutions to monitor understanding.

    After a thorough exploration of ferroelectric devices and their past, this book looks to the industry’s future, assessing market size and remaining reliability/lifetime issues. The author also unveils his strategy for developing "best-selling" ferroelectric devices.

    Kenji Uchino, one of the pioneers in piezoelectric actuators and electro-optic displays, is the director of the International Center for Actuators and Transducers (ICAT) and the professor of electrical engineering at The Pennsylvania State University. He is currently teaching "ferroelectric devices," making use of this book, as well as two other books Micromechatronics and FEM and Micromechatronics with ATILA Software that have been published by CRC Press. He is also the senior vice president and CTO of Micromechatronics Inc., a spin-off company of ICAT, where he is trying to commercialize the ICAT-invented piezoactuators and transducers. He also started teaching "how to start-up a high-tech company" for young engineers using a textbook "Entrepreneurship for Engineers" published by CRC Press. After receiving his PhD from Tokyo Institute of Technology, Japan, Uchino became a research associate in the physical electronics department at the same university. He then joined Sophia University, Japan, as an associate professor of physics in 1985. Subsequently, in 1991, he moved to Pennsylvania. He was also involved with the Space Shuttle Utilizing Committee at the National Space Development Agency (NASDA), Japan, during 1986–1988, and was the vice president of NF Electronic Instruments, United States, during 1992–1994. Uchino has an additional master’s degree in business and administration from St. Francis University, Loretto, Pennsylvania. He has served as a consultant for more than 100 Japanese, U.S., and European industries to commercialize piezoelectric actuators and electro-optic devices. He is the chairman of Smart Actuator/Sensor Study Committee that is partly sponsored by the Japanese government, Ministry of Economics, Trade and Industry (METI). He is also the associate editor of the Journal of Materials Technology (Matrice Technology) and an editorial board member of the Journal of Ferroelectrics (Gordon & Breach) and the Journal of Electroceramics (Kluwer Academic). He has also served as an administrative committee member for IEEE, Ultrasonics, Ferroelectrics, and Frequency Control Society during 1998–2000. Uchino’s research interests are in solid-state physics—especially dielectrics, ferroelectrics, and piezoelectrics, including basic research on materials, device designing, and fabrication processes; he is also interested in the development and commercialization of solid-state actuators and displays for precision positioners, ultrasonic motors, projection-type TVs, etc. He has authored 550 papers, 60 books, and 26 patents on the subject of piezoelectric actuators and optical devices. He has been a fellow of the American Ceramic Society since 1997, and is also a recipient of the SPIE Smart Product Implementation Award (2007), the R&D 100 Award (2007), the ASME Adaptive

    Structures Prize (2005), the Outstanding Research Award from Penn State Engineering Society (1996), the Academic Scholarship from Nissan Motors Scientific Foundation (1990), the Best Movie Memorial Award at the Japan Scientific Movie Festival (1989), and the Best Paper Award from the Japanese Society of Oil/Air Pressure Control (1987). Apart from his academic pursuits, Uchino is an honorary member of KERAMOS (National Professional Ceramic Engineering Fraternity) and has received the Best Movie Memorial Award as the director/producer of several educational videos on "dynamical optical observation of ferroelectric domains" and "ceramic actuators" at the Japan Scientific Movie Festival (1989).
