Abstract : Summary of progress - One actuator module from the last burnout was sintered. It is intact but has some minor cracks. Three other actuators (two with Pt electrodes and one with Au/Pt/Pd electrodes) were burned out and are ready to be CiPped and sintered. Another batch of tape was cast with a 36% volume fraction of binder. Two actuators were made and put into burnout. An actuator (6-65-1) was tested at 3000 psi (to 0.8 MV/m) over the temperature range (-10 deg C to 40 deg C). At 5 deg C, the average strain of the actuator was 460 microstrain.
