Abstract
A shape memory alloy actuator () includes a first part (), a second part (), one or more heat sinks (), and one or more shape memory alloy wires (). The one or more shape memory alloy wires () include a first segment of shape memory alloy wire (). The one or more shape memory alloy wires () are configured to move the second part () relative to the first part () over a range of movement. The first segment () of shape memory alloy wire is connected to the first part () by a first resilient element () at a first end (), and a second end () of the first segment of shape memory alloy wire () is connected to the second part (). The first resilient element () is configured such that in response to a change in tension of the first segment of shape memory alloy wire (), a first distance (d, d) between the first segment of shape memory alloy wire () and at least one of the heat sinks (, N) is increased or decreased by an amount greater than a change in a second distance (I, I) between the first and second ends ().
