Abstract
A method for fabricating a piezoelectric transducer includes depositing a layer of a piezoelectric material on a base using a depositor and applying an electric field to the layer of deposited piezoelectric material in defined locations using an electrode to sinter and pole the deposited piezoelectric material at those defined locations to form a layer of the piezoelectric transducer in a selected shape and with a selected dipole direction.
