Zusammenfassung:A piezoelectric element driving apparatus may apply a predetermined driving signal to a piezoelectric element to drive the piezoelectric element. The driving signal may be an asymmetrical waveform in which amplitudes of first and second polarities thereof are different from each other. An exemplary embodiment in the present disclosure may provide a piezoelectric element driving apparatus and method having a high output while protecting dielectric characteristics of a piezoelectric element by driving the piezoelectric element using an asymmetrical driving signal.
