More Information
Summary:Aspects of the present disclosure relate to a piezoelectric device having at least one piezoelectric element, which has a support plane oriented to a force introduction element, wherein in the event of a thermal loading of the piezoelectric device in the support plane, expansion differences between the piezoelectric element and the force introduction element occur. To compensate for shear loadings, at least one transition element is arranged between the piezoelectric element and the force introduction element, the E-module of which is smaller than the E-module of the piezoelectric element in the support plane.
