Shape Memory Alloy Actuators

SmartFlex® is SAES Getters’ product line of shape memory alloy semi-finishedshapes and components. Shape memory alloys unique property to recover shape upon heating can be ef-fectively packaged into compact, light, powerful and silent actuators to replacealternative technologies based on wax, DC motors and electrical motors. The unmatched energy density, degree of integration and simplicity in designmake shape memory alloys the new industry standard for linear and rotary ac-tuators.

SMA actuators offer a full range of advantages:

Reliability

Compactness and flexibility

Reduced cost

Direct linear or angular movement

Noiseless operation

Compatibility with harsh environments

No EMI

Advantages of SMA Actuators

SAES SmartFlex shape memory alloy wires have been specifically developed foractuators.For linear movements of a few millimeters or angular movements of just a fewdegrees, use of a motor rotating at thousands of rpm coupled with gears, clutch-es and reducers is certainly not the best solution.Replacement of small motors or solenoids can be effectively done withSmartFlex actuator wires. Since shape memory alloy wires are much smaller forthe work they do, a number of new products and improved designs on existingproducts can be developed.Use of “smart materials” for actuation represents a technological opportunity fordevelopment of electro-mechanical components: the typical characteristic ofshape memory alloy wires of obtaining mechanical actions if stimulated withelectrical current promotes development of simple, very compact, reliable actua-tors.Component makers can use SMA materials to simplify products, add new func-tions, upgrade performance, improve reliability and cut down component costs,while significantly reducing mechanical complexity and size.
