Textbook in PDF format 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
