SAES SmartFlex shape memory alloy wires have been specifically developed for actuators.
For linear movements of a few millimeters or angular movements of just a few degrees, use of a motor rotating at thousands of rpm coupled with gears, clutches and reducers is certainly not the best solution.
Replacement of small motors or solenoids can be effectively done with SmartFlex actuator wires. Since shape memory alloy wires presents a very high specific working density, a number of new products and improved designs on existing products can be developed.
Use of "smart materials" for actuation represents a technological opportunity for development of electro-mechanical components: the typical characteristic of shape memory alloys wires of obtaining mechanical actions if stimulated with electrical current promotes development of simple, very compact, reliable actuators.
Component makers can use SMA materials to simplify products, add new functions, upgrade performance, improve reliability and cut down component costs, while significantly reducing mechanical complexity and size.
