Exciter element

Abstract

An exciter element for generating or measuring mechanical movements with an exciter and a receptacle for an object under test and with an electrical inter-face for transmitting the excitation or measurement data and a method for producing such an exciter element, performs reliable measurement or generation in the event of mechanical movements above 100 kHz up to a few megahertz and permits both “out-of-plane” and “in-plane” movements or rotations of the DUT. A flat piezo composite, which is known per se, with a first face lying transverse to the direction of the plate thickness, a second face spaced apart from the first face by the thickness of the plate and lying parallel to the first face, and with rod-shaped piezo elements extending between the first and second face, is used as an exciter.
