Actuator is made of shape memory fibers in elastomer compounds. Prior to embed SMA, a strain of low temperature is applied on them and then the outer surface of the beam is embedded, by applying heat to SMA given that the structural beam is embedded and cannot be return strain recovery are free. have released the tension on the outer surface of pressure will return, this has led to the creation of the beam will be deflection.<br />In this paper, first the relationship of stress - strain- temperature for SMA has been studied. Later, the stress of temperature increase in SMA is calculated based on the theory, differential equations and the beam deflection. Afterward, the experimental tests are performed on smart actuators. Voltage is applied to increase the temperature on SMA in beam and that caused the creation of deflection in beam. This has a fast flexibility, and by controlling the input current to SMA the movement of the beam can be managed.
