Abstract:
In a method for calibrating at least one sensor, wherein the sensor includes at least one piezoelectric element with at least one electrode, and wherein at least one electrode is embodied as a measurement electrode, it is provided as essential to the invention that an electrical excitation voltage is applied to at least one further electrode of the piezoelectric element, embodied as a calibration electrode, to create a mechanical deformation of the piezoelectric element, that the voltage induced by the deformation of the piezoelectric element is captured with at least one measurement electrode, and that the applied excitation voltage and captured voltage are compared.
