Authoritative reference making piezoelectric materials technology more accessible by crossing the boundary between fundamental materials physics and applied engineering Piezoelectric Materials provides a comprehensive overview of the subject, an important class of smart materials which are useful as both actuators and sensors, covering materials, properties, and devices, including case studies of example applications. In addition to providing the underlying science on the subject, the text also supports those interested in using piezoelectric actuators and sensors in real world applications. Early chapters help the reader understand the limits and appropriate operating conditions for the piezoelectric and ferroelectric devices described in later chapters. Other topics discussed in Piezoelectric Materials include: The range of piezoelectric and ferroelectric materials and their fundamental properties and applications in sensors, actuators, and as energy harvesting elements. Designs for various piezoelectric devices, including case studies on piezoelectric actuator applications, e.g., for servovalves, hydrophones, and active vibration control. Key limits of these materials and fundamental equations to predict displacement, force, resonance, and power requirements. Piezoelectric Materials serves as an invaluable reference on the subject and makes piezoceramic materials technology more accessible to researchers, advanced students, and practicing engineers. The text is also helpful to those in industries using piezoelectrics, in particular manufacturers of optics, photonics, and nanometrology equipment.
