Abstract
A piezoelectric drive having an excitation piezoelement ( ) and a resonator ( ). The resonator is coupled to the piezoelement and is in interactive connection with a body ( ) to be driven. The resonator ( ) has a mass distribution that is designed such that, as a result of an excitation oscillation by the piezoelement ( ), the resonator ( ) begins to asymmetrically oscillate in several directions dependent on the frequency of the excitation oscillation. The asymmetric oscillations, via the interactive connection, displace the body to be driven into a directed movement.
