Abstract
A method of making a print head (100) includes forming a body (110) having a closed base (120) and independent fluid containment compartments (220) formed about the closed base (120). A substantially planar piezoelectric transducer (80) comprising a slab (60) of piezoelectric material provides a means of enclosing each of the independent fluid containment compartments (220). Each of the independent compartments has operably associated therewith one of a plurality of first electrodes (20) arranged on a first surface (62) of the slab (60) of piezoelectric material and a portion of a second electrode (22) arranged on an opposite second surface (64). By applying a voltage to the first and second surface electrodes (20, 22) in a predetermined manner induces an electric field in a portion of the slab (60) of piezoelectric material and thereby forces fluid composition through the independent fluid containment compartment (220).
