Ferroelectricityhasbeen one ofthe most used and studiedphenomenain both scien‐

to optical or memory devices. Since the discovery of ferroelectricity in Rochelle Salt

The present volume focuses on the applications of ferroelectric materials, describing
innovativesystemsthatuseferroelectricity.Thecurrentuseofsuchdevicesassensors
and actuators, in the field of acoustics, MEMS, micromotors and energy harvesting
will be presented in chapters 1 to 5. The next sectionproposes a particular emphasis
