Abstract
A system may include an actuation member having a first end and a second end. A length of the actuation member is greater than a width of the actuation member. The length extends from the first end to the second end along a longitudinal axis when the actuation member is undeformed. The actuation member may include a magnetic shape memory alloy. The system may further include an anchor retaining the first end of the actuation member. The second end of the actuation member may be free to move laterally to the longitudinal axis in response to a deformation of the actuation member. The system may also include a magnetic field source in proximity to the actuation member. The magnetic field source may be configurable to alter a magnetic field applied to the actuation member to adjust the extent of deformation of the actuation member.
