This book presents recent research in the field of piezoelectric vibration energy harvesting in
which intentionally designed nonlinearities as well as inherently present are widely
considered. It provides an overview of the state-of-the-art with a sharp classification into
linear and nonlinear devices and recalls the fundamentals of piezoelectricity and
magnetostatics. A detailed treatment of linear and nonlinear mathematical modeling of
piezoelectric harvesters is then developed to provide the reader with a wide range of modeling
possibilities. Theoretical computational and experimental approaches to modeling the magnetic
interaction are also provided. Several cases of innovative piezoelectric harvester designs
based on magnetic interaction as a frequency up-conversion mechanism (FuC) are developed.
Improvements of the magnetic FuC are proposed in combination with indirect impacts as well as
the manipulation of magnetic forces with novelty methods. Novel studies on the magnetic
interaction itself and its implications for the dynamic behavior of the harvester are also
summarized. The book provides an integrated view of theoretical computational and
experimental research in this field as such it can be useful for researchers interested in
linear and nonlinear piezoelectric energy harvesting for graduate courses on smart structures
and devices microsystems and for designers.
