Patent Number Title Of Patent Date Issued
4958100 Actuated truss system September 18, 1990
A truss member includes a piezoelectric stack and a cylindrical shell formed of composite material surrounding the stack and bonded thereto, such that the axial load is distributed between the shell and the stack. The truss is fitted to a structural assembly via end pieces, and elect
4849668 Embedded piezoelectric structure and control July 18, 1989
A composite structural member includes multiple layers with one or more embedded piezoelectric elements. In a conductive member, an insulating sheath electrically isolates each piezoelectric element while mechanically coupling it to the surrounding layers, forming a unitary structure wit
