  text: The increasingly simulation-driven design process of ultrasonic transducers
    requires several reliable parameters for the description of the material behaviour.
    Exact results can only be achieved when a single specimen is used in the identification
    process, which typically is prone to the problem of low sensitivities to certain
    material parameters and thus high uncertainties. Therefore, a custom electrode
    topology for increased sensitivity is proposed for a piezoceramic disc. The thereupon
    conducted measurements of the electric impedance can be used as a starting point
    for an inverse approach where an equivalent simulation model is used to identify
    fitting material parameters. An optimisation strategy based on a preliminary sensitivity
    analysis is presented that leads to a good agreement between measurement and simulation.
    Furthermore, the proposed measurement procedure is able to evaluate the quality
    of the simulation model. Hence, different frequency-dependent damping models are
    presented and evaluated.
