Piezo actuators for weight-sensitive
applications
Dynamic Structures and Materials introduces 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 10microns to 10mm The use of flexure guidance enables motion that is free of backlash and friction

Stress testing at the nano scale
Material stress testing tool incorporates a flexure-based piezoelectric positioner, a capacitive probe displacement sensor, and a high-resolution load cell for testing of thin films under stress
The FPA-180E piezo actuator provides 180microns of displacement range in a 6gram titanium package of less than 8x9x26mm in size.
The stiffness of the FPA-180E is 0.39N/micron, 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 8x10x17mm in size.
The corresponding stroke, stiffness, and unloaded natural frequency are 80microns, 0.5N/micron, 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 upon request.
