DSM Releases New Miniature Piezoelectric Actuators for Weight-Sensitive and Space-Sensitive Applications

Franklin, TN - June 2006

New product announcement: Dynamic Structures and Materials, LLC (DSM) is pleased to introduce two ultra-compact piezoelectric actuators or stages for weight-sensitive and space-sensitive applications. These flexure-guided mechanisms are new additions to DSM's line of piezoelectric positioning actuators, which currently offers a range of motion from 10 microns to 10 mm. The use of flexure guidance enables motion that is free of backlash and friction.

The FPA-180E piezo actuator provides 180 microns of displacement range in a 6 gram titanium package of less than 8 x 9 x 26 mm in size. The stiffness of the FPA-180E is 0.39 N/micron, and the device offers a fast dynamic response through an unloaded natural frequency of 1325 Hz.

The FPA-80E is a slightly different stage construction of stainless steel that measures 8 x 10 x 17 mm in size. The corresponding stroke, stiffness, and unloaded natural frequency are 80 microns, 0.5 N/micron, and 1700 Hz, respectively.

Similar to DSM's other piezoelectric actuators, the FPA-180E and the FPA-80E's construction materials are compatible with clean room and vacuum environments. This type of preloaded, flexure-guided actuator design is readily adaptable into a variety of applications including miniature valves, optical switching and scanning, and nanopositioning. DSM's actuators are typically supplied with piezo material rated for -30/150V operation, but other materials and custom designs are available upon request.
