As previously reported, a NASA Langley-developed electroactive polymer-ceramic hybrid system (HYBAS) has demonstrated significant enhancement in actuating displacement. The displacement of the system is derived from both the electrostrictive polymer and from single crystal elements. The electroactive elements are driven by a single power source. Recently, a modification of HYBAS has been made to increase the capability of air driving for synthetic jet devices (SJ) used in aerodynamic control technologies. The dependence of the air driving capability of the modified HYBAS on the configuration of the actuating device has been investigated. For this particular application, the modified HYBAS demonstrated a 50% increase in the volume change in the synthetic jet air chamber, as compared with that of the HYBAS without the modification.
