High strain lead-based perovskite ferroelectrics

High strain piezoelectric ceramics are state of the art materials for
high precision positioning devices. Different material systems under
investigation, attempts to further improve the strain behavior by
formation of textured microstructures and the possibilities to increase
the operation temperature are reviewed. Furthermore, an analysis is
given of recent advances to achieve a better understanding of the
microscopic mechanisms contributing to the macroscopic strain behavior.
