ABSTRACT:
An actuation device having a shape memory alloy component containing: a base having a bottom portion, at least one first magnetic component disposed under the bottom portion of base, a carrier having a top portion, at least one second magnetic component which is disposed on the top portion of carrier and which corresponds in location to the first magnetic component, and a shape memory alloy component which is disposed between the base and the carrier. Shape memory alloy component has at least one deformable supporting component, which is disposed at a position corresponding to both positions of the first magnetic component and of the second magnetic component, for supporting the carrier. The supporting component is in a horizontal form between the base and the carrier since there is a magnetic force between the first magnetic component and the second magnetic component.
