  • Method for activating an electromechanical element
    Patent number: 11303226
    Abstract: The invention relates to a method for activating at least one portion, to be specific a change portion, of an electromechanical element (3), comprising the following steps: providing an electromechanical element, wherein at least the change portion has at least two electrodes, which are spaced apart from one another, and arranged between the electrodes a polycrystalline and ferroelectric or ferroelectric-piezoelectric material with a multiplicity of domains, wherein, in an initial state, at least some of the domains have directions of polarization that are different from one another; generating an electrical field between the electrodes of the change portion by applying an electrical voltage in the form of at least one voltage pulse with a defined amplitude and a defined duration; transforming some of the domains with directions of polarization that are different from one another into a state of the same direction of polarization as a result of the at least one voltage pulse, and thereby producing an increase
