Piezoelectric Materials, Composites, and Devices: Fundamentals, Mechanics, and Applications provides insight on developing and applying optimal piezoelectric devices with high performance and durability. Overviews of the fundamentals of piezoelectricity, piezoelectric parameters, and common characterization techniques are given, as are examples of the structures and properties of piezoelectric ceramics, polymers, their composites, and lead-free piezoelectric materials. Reliable characterization of piezoelectric materials and composites by combining numerical simulations with appropriate measurements is covered as well. Basic equations and modeling approaches are presented, making it easier to understand the stress and electric fields of piezoelectric devices. Piezoelectric Materials, Composites, and Devices: Fundamentals, Mechanics, and Applications also covers piezoelectric energy harvesters, piezoelectric biosensors, as well as the performance of advanced piezoelectric devices. The final part of the book concentrates on reliability and durability (fracture and fatigue) of piezoelectric materials and composites.
