Abstract:
A method for processing a ring type piezoelectric device comprises: providing a ring type piezoelectric embryo; printing at least a pair of electrodes to divide the ring type piezoelectric embryo into a plurality of equal sections; and immersing the divided ring type piezoelectric embryo into high temperature silicon oil with high voltage for polarization so as to make the polarization of the ring type piezoelectric device perpendicular to a cross-section thereof.
