Short summary

This article describes a method to measure the parameters of piezoelectric materials. This is done by evaluating the complex electrical resistance of a sample. However, the properties of the material can not be calculated directly from the electrical resistance. Instead, a simulation model of the sample is created, and the parameters of the simulation model are adapted using an optimisation algorithm until the model's resistance and the resistance of the physical sample match.
