<p>The present invention relates to an actuator including an actuating element for producing motion and/or force. The actuating element comprises material having a twinned structure. It is possible to change the proportions of the twin variants with a magnetic field, induced by at least one source of a magnetic field. The actuator is suitable for a number of applications including pumps, motors, injectors and the like applications where motion and/or force is needed. <IMAGE></p> |
