Abstract
A piezoelectric actuator includes a deflectable membrane and a piezoelectric element attached to a part of the deflectable membrane for exerting a mechanical force on the deflectable membrane. The piezoelectric element is operable to perform an expansion and a contraction motion depending on an electric field applied to the piezoelectric element. The piezoelectric element leaves open a central region of the deflectable membrane and has a peripheral outline that does not coincide with an outline of the deflectable membrane.
