Piezoelectricity has been a steadily growing field, with recent advances made by researchers from applied physics, acoustics, materials science, and engineering. This collective work presents a comprehensive treatment of selected advanced topics in the subject. Every chapter is self-contained and written by international experts who elaborate on special topics. This book is written for an intermediate graduate level and is intended for researchers, mechanical engineers, and applied mathematicians interested in the advances of piezoelectricity and its new applications, and may be used as a supplemental text to a course where piezoelectricity is a focus.
