More Information
Summary:A first metal layer 23 is deposited on a first side of a piezoelectric composite 22 to form a common electrode, a second metal layer 25 is provided over the opposite side and a thicker third metal layer 26 may be provided over the second metal layer 25. Portions of the second metal layer are removed to create a plurality of individual electrodes (fig 4B). The individual electrodes extend 24 beyond the piezoelectric composite 22 in the elevation direction to create an improved attachment contact point for electrode leads. The metal layers may be provided by lithography, a wireframe or a foil sheet. Several array shapes are discussed (figs 6, 7, 10). The transducer array is intended for downhole use (figs 10, 11).
