Piezo-Active Composites

This book is devoted to the systematic description of the role of microgeometry of modern piezo-active composites in the formation of their piezoelectric sensitivity. In five chapters, the authors analyse kinds of piezoelectric sensitivity for piezo-active composites with specific connectivity patterns and links between the microgeometric feature and piezoelectric response. The role of components and microgeometric factors is discussed in the context of the piezoelectric properties and their anisotropy in the composites. Interrelations between different types of the piezoelectric coefficients are highlighted. This book fills a gap in piezoelectric materials science and provides readers with data on the piezoelectric performance of novel composite materials that are suitable for sensor, transducer, hydroacoustic, energy-harvesting, and other applications.

Analyzes interrelations between the piezoelectric coefficients for specific connectivity patterns Highlights the role of microgeometry in the formation of high piezoelectric sensitivity Provides examples of the piezoelectric performance to help the reader to select novel composites

From 1996 to 1998, he was a Senior Scientist at the Defence Evaluation and Research Agency (DERA), Functional Materials Group, UK working on ferroelectric ceramics and composites. He joined the University of Bath, UK in August 1998, and now he is a Professor at the same University. The research interests of Dr. C. R. Bowen are concerned with modern functional materials, including ferroelectric ceramics and piezo-active composites for modern sensors and actuators, as well as with manufacturing and characterisation of these materials. Continuing interest includes the use of piezoelectric materials combined with structural composites, such as bistable laminates, for energy harvesting and shape changing applications. Additional interest is concerned with pyroelectric materials, their performance and use in energy-harvesting applications. Dr. C. R. Bowen earned the Thornton and Hazelwood prizes for academic work (19861990), Institute of Materials National Lecture Competition award (1993), SET award (2002), and John Willis award for excellence in research and teaching (2003). Dr. C. R. Bowen has published three monographs and over 250 scientific papers, conference proceedings, and abstracts. He has been awarded an ERC Advanced Fellowship in Novel Energy Materials, Engineering Science and Integrated Systems (NEMESIS, Grant Agreement No. 320963).
