Abstract

Enhanced displacement actuators that utilize bending, such as unimorphs and bimorphs, employ piezoelectric elements having a regular shape, such as a plate or disk. With advances in Solid Freeform Fabrication, the ability to produce actuators having novel geometries allows the designer to further enhance actuator displacement through the intelligent design of the piezoelectric element. Recent studies have shown that spiral shaped actuators produce very large displacements. Numerical analysis into the mechanisms of this enhanced displacement have been conducted and the results of these parametric studies are presented.
