Preface

Ferroelectricity has been one of the most used and studied phenomena in both scien‐
tific and industrial communities. Properties of ferroelectrics materials make them par‐
ticularly suitable for a wide range of applications, ranging from sensors and actuators 
to optical or memory devices. Since the discovery of ferroelectricity in Rochelle Salt 
(which used to be used since 1665) in 1921 by J. Valasek, numerous applications using 
such an effect have been developed. First employed in large majority in sonars in the 
middle of the 20th century, ferroelectric materials have been able to be adapted to more 
and more systems in our daily life (ultrasound or thermal imaging, accelerometers, gy‐
roscopes, filters…), and promising breakthrough applications are still under develop‐
ment (non‐volatile memory, optical devices…), making ferroelectrics one of tomor‐
row’s most important materials. 
The purpose of this collection is to present an up‐to‐date view of ferroelectricity and its 
applications, and is divided into four books: 
 Material Aspects, describing ways to select and process materials to make 
them ferroelectric. 
 Physical Effects, aiming at explaining the underlying mechanisms in ferroelec‐
tric materials and effects that arise from their particular properties. 
 Characterization and Modeling, giving an overview of how to quantify the 
mechanisms of ferroelectric materials (both in microscopic and macroscopic 
approaches) and to predict their performance. 
 Applications, showing breakthrough use of ferroelectrics. 
Authors of each chapter have been selected according to their scientific work and their 
contributions to the community, ensuring high‐quality contents. 
The present volume focuses on the applications of ferroelectric materials, describing 
innovative systems that use ferroelectricity. The current use of such devices as sensors 
and actuators, in the field of acoustics, MEMS, micromotors and energy harvesting 
will be presented in chapters 1 to 5. The next section proposes a particular emphasis
X Preface

on the application of ferroelectric materials as transistors and memory devices (chap‐
ters 6 to 11), showing one of the future breakthrough uses of these materials. 
I sincerely hope you will find this book as enjoyable to read as it was to edit, and that 
it will help your research and/or give new ideas in the wide field of ferroelectric mate‐
rials. 
Finally, I would like to take the opportunity of writing this preface to thank all the au‐
thors for their high quality contributions, as well as the InTech publishing team (and 
especially the publishing process manager Ms. Silvia Vlase) for their outstanding sup‐
port.
