The ceramic manufacturing process is so complicated and process-dependent, that achieving reproducibility is very hard in many cases. Especially, ceramic resonator is smaller than other piezoelectric ceramics applications and more precise process control is needed. Therefore, understanding configuration design and tendency through simulation is very useful to avoid unnecessary effort. In recent trend, as piezoelectric ceramics is used in the various actuators and sensors, the use of simulation in this field is also increasing. Some of actuator, sensor or acoustic applications may have a complicated shape depending on the purposes, however, basic simulation process was regarded as same as resonator. Therefore, the accuracy of simulation depends on the accuracy of the knowledge on the material constants of piezoelectrics.

This book introduces piezoelectric microelectromechanical (pMEMS) resonators to a broad audience by reviewing design techniques including use of finite element modeling, testing and qualification of resonators, and fabrication and large scale manufacturing techniques to help inspire future research and entrepreneurial activities in pMEMS. The authors discuss the most exciting developments in the area of materials and devices for the making of piezoelectric MEMS resonators, and offer direct examples of the technical challenges that need to be overcome in order to commercialize these types of devices. Some of the topics covered include: Widely-used piezoelectric materials, as well as materials in which there is emerging interest Principle of operation and design approaches for the making of flexural, contour-mode, thickness-mode, and shear-mode piezoelectric resonators, and examples of practical implementation of these devices Large scale manufacturing approaches, with a focus on the practical aspects associated with testing and qualification Examples of commercialization paths for piezoelectric MEMS resonators in the timing and the filter markets ...and more! The authors present industry and academic perspectives, making this book ideal for engineers, graduate students, and researchers.

This volume contains the proceedings of the 10th edition of the International Conference on Simulation of Semiconductor Processes and Devices (SISPAD 2004), held in Munich, Germany, on September 2-4, 2004. The conference program included 7 invited plenary lectures and 82 contributed papers for oral or poster presentation, which were carefully selected out of a total of 151 abstracts submitted from 14 countries around the world. Like the previous meetings, SISPAD 2004 provided a world-wide forum for the presentation and discussion of recent advances and developments in the theoretical description, physical modeling and numerical simulation and analysis of semiconductor fabrication processes, device operation and system performance. The variety of topics covered by the conference contributions reflects the physical effects and technological problems encountered in consequence of the progressively shrinking device dimensions and the ever-growing complexity in device technology.

The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.

Piezoelectric Ceramics focuses on the relationship between piezoelectricity and ferroelectricity as they apply to ceramics, taking into consideration the properties of materials that are being used and possibly be used in the industries. Composed of 12 chapters, the book starts by tracing the history of piezoelectricity and how this affects ceramics. The different measurement techniques are discussed, including dielectric, ferroelectric, and piezoelectric measurements. The book proceeds by discussing Perovskite structure and barium titanate. Covered areas include electric field, piezoelectric properties, particle size effect, and dielectric strength. The properties, compositions, and reactions of various perovskites are discussed. Numerical analyses are presented in this regard. The book also offers interpretations of the experiments conducted. The discussions end with the processes involved in the manufacture and applications of piezoelectric ceramics. Concerns in manufacturing include calcination, grinding, mixing, electroding, firing, and quality control. Piezolectric ceramics are applied in air transducers, instrument transducers, delay line transducers, underwater sound ultrasonic power, and wave filters. The book is important for readers interested in doing research on ceramics.
