Piezoelectric actuator
LPA Series 100 µm DSM

DSM's LPA FlexFrame PiezoActuator™ products are flexure-guided lever mechanisms that mechanically amplify the motion of the integrated piezoelectric ceramic. DSM's LPA designs span a range of displacement capabilities up to 1mm.

The actuator frame is typically a monolithic piece of stainless steel or titanium alloy, and it can include threaded or through holes for attachment at the actuator's output. For mounting purposes, the frame can be designed with threaded holes in the bottom or side structure.

The moving mass in a LPA actuator is typically less than that of other types of mechanically amplified mechanisms. Consequently, the LPA architecture can enable relatively higher dynamic response performance.

The LFPA FlexFrame PiezoActuator™ products include a secondary mechanical amplification to attain relatively larger motion ranges up to 10mm. In order to satisfy a non-magnetic requirement for use in magnetic resonance imaging (MRI) applications, DSM has fabricated LFPA mechanisms from titanium alloy.
