摘要： A driving circuit (21) of a shape memory alloy actuator of the present invention measures by a measurement part a parameter value corresponding to a target position of a moving part that is displaced by being driven on account of the expansion and contraction of an SMA (15), which expands and contracts with temperature changes and which exhibits hysteresis in a parameter-distortion characteristic relating to the expansion and contraction, while the temperature of the SMA (15) is being raised or lowered. The driving circuit (21) sets the measured parameter value as a target parameter. The temperature of the SMA (15) is raised or lowered such that the parameter value measured by the measurement part passes the target parameter, before the crystal phase of the SMA (15) becomes a martensitic phase. Thereafter, the temperature of the SMA (15) is raised or lowered again such that the parameter value measured by the measurement part reaches the target parameter.

摘要： A camera lens actuation apparatus for driving motion of a camera lens supported on a support structure by a suspension system. The apparatus incorporates a subassembly comprising SMA wire connected to at least one mounting member which is mounted to the support structure. At least one pair of lengths of SMA wire are held in tension between the camera lens element and the support structure at respective acute angles to the optical axis applying a tensional force having a component along the optical axis. The lengths of SMA wire in the pair are held at angle as viewed along the optical axis. There may be plural pairs with a balanced arrangement in which the forces generated have no net component perpendicular to the optical axis and generate no net torque around any axis perpendicular to the optical axis. A control circuit controls heating of the SMA wire in response to a measure of its resistance.

摘要： A shape memory alloy actuation apparatus comprises a camera lens element supported on the support structure by a plurality of resilient flexures that guide movement of the movable element along the optical axis. A shape memory alloy actuator biassed by the resilient flexures and an additional resilient biassing element is arranged to drive movement of the camera lens element. An end-stop limits movement of the camera lens element at a position where the shape memory alloy actuator has a predetermined length that is above the length corresponding on the local maximum resistance by an amount not greater than 15% of the difference between (i) the length corresponding to the local maximum resistance and (ii) the length corresponding to the local minimum resistance.
