Abstract
The present work deals with the development of a macroscopic continuum model to investigate the influence of the flexoelectric effect on microstructural domain switching processes in ferroelectric ceramics. It is of interest whether direct flexoelectricity can initiate a poling process in piezoceramics and if indirect flexoelectricity can improve the actuator performance of an IDE wafer.
