ABSTRACT:
A structure includes a foundation member and multiple piezoelectric actuator/sensor elements disposed transversely about the structure. The elements are bound to the face of the foundation member to permit force transmission between the elements and the foundation member. The elements include restriction plies orientated oppositely for alternating transverse elements. The elements have a preferred direction of motion and when two adjacent elements are oppositely poled, this relates to a torsional motion between the elements and the foundation member. When four elements are spaced about a cylindrical foundation member and selectively poled, axial, bending and torsional motion between the elements and foundation member is effected.
