Abstract

A ferroelectric device includes a first electrode, a second electrode spaced apart from the first electrode, and a ferroelectric element arranged between the first and second electrodes. The ferroelectric element has a plurality of quasistatic strain configurations that are selectable by the application of an electric field and the device has selectable electromechanical displacement by the application of the electric field.
