Abstract
In a shape memory alloy actuator driving device, a predetermined constant current is applied to a shape memory alloy member as a retrieval signal to detect a terminal voltage of the shape memory alloy member, and a detection result of the terminal voltage is compared with a target voltage value to be calculated based on a target resistance value of the shape memory alloy member and a value of the constant current to cause a driving circuit to output, to the shape memory alloy member, a drive current that makes the detection result substantially equal to the target voltage value.
