Download or read book Piezoelectric Actuators and Ultrasonic Motors written by Kenji Uchino and published by Springer Science & Business Media. This book was released on 1996-11-30 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remarkable developments have taken place in the field of mechatronics in recent years. As symbolized by the "Janglish (Japanese English)" word, mechatronics, the technology and the social adaptation for introducing electronics into mechanics has been readily accepted in Japan. Currently robots are producing many products under computer control in Japanese factories, and supermarkets are utilizing automation systems for sample displays and sales. Further, the fast paced change in semiconductor chip technology has given rise to the need for micro-displacement positioning techniques. Actuators utilizing piezoelectridelectrostrictive effects are expected to meet these needs in mechanical components in the next micro mechatronic age. This book, in English, builds on my earlier publications concerned with ceramic actuators. The first edition titled "Essentials for Development and Applications of Piezoelectric Actuators" was published in 1984 through the Japan Industrial Technology Center. The second edition "PiezoelectriclElectrostrictive Actuators" published in Japanese through Morikita Pub. Co. (Tokyo) became one of the best sellers in that company in 1986, and was then translated into Korean. The problem solving edition "Piezoelectric Actuators -Problem Solving" was also published through Morikita, which was sold in conjunction with a 60 minute video tape to provide easy understanding.

Download or read book High Power Piezoelectrics and Loss Mechanisms written by Kenji Uchino and published by CRC Press. This book was released on 2020-09-09 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the pioneers of "Piezoelectric Actuators", I have contributed to the commercialization of various products for over 45 years, including million-selling devices, micro-ultrasonic motors for smart-phone camera modules by Samsung Electromechanics, piezoelectric transformers for backlight inverters by Apple laptops, multilayer PZT actuators for diesel injection valves by Denso Corporation, and piezoelectric energy harvesting modules for Programable Air-Burst Munition by the US Army. During the development period for "piezoelectric actuators and transformers," I found that the bottleneck for device miniaturization was heat generation under a high-power drive condition. Thus, in parallel to the piezo-actuator developments, I have been developing various high-power density piezo-ceramic materials with the loss mechanism clarification. Hence, I considered that it was time to organize a textbook based on the previous studies, including my materials development philosophy to stimulate younger generations to reach to the energy density of up to 100 W/cm3 in the future. Increasing efficiency and saving energy and space (compactness) are one of the important approaches in this 21st-century "sustainable society." High-Power Piezoelectrics and Loss Mechanisims introduces the theoretical background of piezoelectrics, electromechanical phenomenology, loss mechanisms, practical materials, device designs, drive and characterization techniques, and typical applications, and looks forward to the future perspectives in this field. This book is NOT an overall review of this area, but it focuses on important and basic ideas under my development philosophy to understand how to design and develop high-power piezoelectric materials and devices. This textbook is designed for self-learning by the reader aided by the availability of: • Chapter Essentials – Summary for quick memory recovery • Check Points – Answers are provided in the Appendix • Example Problems – To enhance the reader’s understanding with full, detailed solutions • Chapter Problems – For the final exam or further consideration

Book excerpt: This book provides a completely up-to-date survey of the many different types of ultrasonic motors currently in use. These motors, which use ultrasonic vibrations to produce a frictional driving force, have many attractive features, including simple structures which can easily be miniaturized, large power to weight ratios, high torque at low speed, high precision due to low inertia and easy electronic control, and no associated magnetic field. With such advantages, they are increasingly displacing conventional electromagnetic motors in robot actuators, camera autofocus mechanisms, and aerospace devices, to name a few examples. Written by leading experts on the subject, the book introduces the reader to the design and manufacture of the motor as well as to techniques for evaluating motor performance. It will be an invaluable guide to electrical engineering researchers, designers, and manufacturers.

Book excerpt: After Uchino’s introduction of a new terminology, ‘Micromechatronics’ in 1979 for describing the application area of ‘piezoelectric actuators’, the rapid advances in semiconductor chip technology have led to a new terminology MEMS (micro-electro-mechanical-system) or even NEMS (nano-electro-mechanicalsystem) to describe mainly thin film sensor/actuator devices, a narrower area of micromechatronics coverage. New technologies, product developments and commercialization are providing the necessity of this major revision. In particular, the progresses in high power transducers, loss mechanisms in smart materials, energy harvesting and computer simulations are significant. New technologies, product developments and commercialization are providing the updating requirement for the book contents, in parallel to the deletion of old contents. Various educational/instructional example problems have been accumulated, which were integrated in the new edition in order to facilitate the self-learning for the students, and the quiz/problem creation for the instructors. Heavily revised topics from the previous edition include: high power transducers, loss mechanisms in smart materials, energy harvesting and computer simulations New technologies, product developments and commercialization helped shape the updated contents of this book where all chapters have been updated and revised.

Download or read book Piezoelectricity written by Walter Heywang and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discovered in 1880, piezoelectric materials play a key role in an innovative market of several billions of dollars. Recent advances in applications derive from new materials and their development, as well as to new market requirements. With the exception of quartz, ferroelectric materials are used for they offer both high efficiency and sufficient versatility to meet adequately the multidimensional requirements for application. Consequently, strong emphasis is placed on tailoring materials and technology, whether one deals with single crystals, ceramics or plastic materials. Tailoring requires a basic understanding of both physical principles and technical possibilities and limitations. This report elucidates these developments by a broad spectrum of examples, comprising ultrasound in medicine and defence industry, frequency control, signal processing by SAW-devices, sensors, actuators, including novel valves for modern motor management. It delivers a mutual fertilization of technology push and market pull that should be of interest not only to materials scientists or engineers but also to managers who dedicate themselves to a sound future-oriented R&D policy.
