More Information
Summary:Disclose displacement connectors of high bending stiffness, high-performance piezoelectric actuators and derivative devices made of such. The connector has circumferentially alternating recess housings which, when fitted with the intended piezoelectric active elements makes displacement actuators, approximately double (2×), triple (3×) or quadruple (4×) the displacement of individual active elements without adversely jeopardizing their regenerative forces. The connector may take any overall cross-section and length to suit intended applications. Connector recesses can be configured to house piezoelectric elements of a wide variety of cross-sections and dimensions, including longitudinal mode stacks, transverse mode bars and/or tubes, single crystal blocks of suitable cut and dimensions and their bonded assemblages.
