| Abstract | A piezoelectric actuator with integrated features to provide coarse position adjustment of a pushing threaded rod and also mechanically amplified piezo motion for fine position adjustment is presented here in three design variants. The mechanical amplifier houses one or more piezo stacks in longitudinal axis with preload to translate an amplified motion in the order of a few times in the transverse axis, perpendicular to the piezo stack motion. The piezo amplifier output travel is transmitted to the threaded rod with a ball at the end to push a desired surface for position adjustments and motion translation in application such as a mirror mount. |
