The inhomogeneous strain induced by an external electric field (the converse flexoelectric effect) has been studied in thin KTaO3 single crystal plates by a scanning interferometric microscopy method. It has been shown that the type of inhomogeneous strain (spherical and cylindrical bending) is determined by the direction of the applied field along [001] and [011] crystallographic directions.
