Piezoelectric materials and shape memory alloys (SMAs) are very common materials for actuators and sensors; however their composites as electrical generators are least explored, although the use of piezoelectric materials as the mechanical energy harvester is becoming popular. In this dissertation piezoelectric material and SMA are used as constituents for an active composite of two types; one is a composite of piezoelectric material and SMA as an actuator and the second one is a composite as a thermal energy harvester. The analytical modeling and experimental study related to Piezo-SMA active composites are examined for both cases. Eshelby's inclusion problems are combined into a single model to treat the coupled behavior of electro-mechanics inherent in the piezo-SMA composite where the piezo is matrix phase and SMA is filler phase. SMA undergoes phase transformation such as stress-induced martensite transformation and temperature induced austenite transformation. Basic design and experimental work done on active composite are discussed in the areas of material characterization and mechanical modeling.

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.

Piezoelectric Aeroelastic Energy Harvesting explains the design and implementation of piezoelectric energy harvesting devices based on fluid-structure interaction. There is currently an increase in demand for low power electronic instruments in a range of settings, and recent advances have driven their energy consumption downwards. As a result, the possibility to extract energy from an operational environment is of growing significance to industry and academic research globally. This book solves problems related to the integration of smart structures with the aeroelastic system, addresses the importance of the aerodynamic model on accurate prediction of the performance of the energy harvester, describes the overall effect of the piezoelectric patch on the dynamics of the system, and explains different mechanisms for harvesting energy via fluid-structure interaction. This wealth of innovative technical information is supported by introductory chapters on piezoelectric materials, energy harvesting and circuits, and fluid structure interaction, opening this interdisciplinary topic up for readers with a range of backgrounds. Provides new designs of piezoelectric energy harvesters for fluid-structure interaction Explains how to correctly model aerodynamics for effective aeroelastic energy harvesting Numerical examples allow the reader to practice the design, modeling and implementation of piezoelectric energy harvesting devices
