This book presents new approaches to R&D of piezoelectric actuators and generators of different types based on established, original constructions and contemporary research into framework of theoretical, experimental, and numerical methods of physics, mechanics, and materials science. Improved technical solutions incorporated into the devices demonstrate high output values of voltage and power, allowing application of the goods in various areas of energy harvesting. The book is divided into seven chapters, each presenting main results of the chapter, along with a brief exposition of novel findings from around the world proving context for the author’s results. It presents particular results of the Soviet and Russian schools of Mechanics and Material Sciences not previously available outside of Russia.
Explains original theoretical and experimental methods developed for solution of energy harvesting problems
Facilitates improvement and optimization of energy harvesting devices and systems based on important numerical results
Describes promising new experimental equipment, supported by Russian patents, for testing and studying piezoelectric actuators and generators
