Piezoelectric actuators are small and
light
Ultracompact piezoelectric actuators or stages suit weight-sensitive and space-sensitive applications.
Dynamic Structures and Materials has released two ultracompact 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 10um to 10mm

Three high-power benchtop piezoelectric amplifier and controller products are used to drive piezoelectric materials in micropositioning, nanopositioning and ultrasonic applications.
The use of flexure guidance enables motion that is free of backlash and friction.
The FPA-180E piezo actuator provides 180um of displacement range in a 6g titanium package of less than 8 x 9 x 26mm in size.
The stiffness of the FPA-180E is 0.39N/um, and the device offers a fast dynamic response through an unloaded natural frequency of 1325Hz.
The FPA-80E is a slightly different stage construction of stainless steel that measures 8 x 10 x 17mm in size.
The corresponding stroke, stiffness, and unloaded natural frequency are 80um, 0.5 N/um and 1700Hz, 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 on request.
