Abstract
In the method for monitoring flexural vibrations of a piezoactuator, a small-signal spectrum of a piezoactuator, which is provided and mounted for the purpose of exciting longitudinal vibrations, is measured and an excitation of a transverse vibration in the piezoactuator is detected from resonances occurring in the small-signal spectrum.
