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