(US5755909-A)      A method is claimed for applying electrodes to the surface of a ceramic piezoelectric layer, comprising the steps: a) forming a pattern of deformable electrode material on the surface of a deformable film; b) interposing an adhesive layer between the pattern of deformable electrode material and the surface of a ceramic piezoelectric layer; and c) pressing deformable electrode material against the ceramic piezoelectric layer with a pressure which is uniform across the surface of a ceramic piezoelectric layer. An electroded piezoelectric transducer comprising: i) a ceramic piezoelectric layer (10) having a surface containing granular asperities; ii) a pattern of deformable electrode material (30, 31) having portions which are deformed to conform to the granular asperities; and iii) an adhesive layer (22) bonding the surfaces of the deformable electrode material and the ceramic piezoelectric layer in the regions between the peaks of the granular asperities. An ink jet print-head comprising a ceramic piezoelectric transducer layer, a pattern of deformable electrode material bonded to a surface thereof, and a chamber plate. The surface of the chamber plate is formed with ink pressure chambers affixed to the ceramic piezoelectric layer, the ink pressure chambers being located at positions corresponding to the electrodes in the deformable electrode material.    USE -   Useful in applying electrodes to ceramic piezoelectric transducers, eg. shear-mode transducers of the type used in ink jet systems.    ADVANTAGE -   The piezoelectric transducers do not require the complex and expensive electrode-forming procedures of the prior art. The method avoids the need for wiring connections at the surface of the piezoelectric transducer.
