Abstract

The present techniques generally relate to shape memory alloy actuators, and for methods of manufacturing such SMA actuators. We describe a shape memory alloy (SMA) actuator comprising a static element (104); a moveable element (106) which is moveable relative to the static element; and a plurality of SMA wires (108) which are each connected to one or both of the static element and the moveable element and which on contraction cause movement of the moveable element. At least one connector (110a, 110c), preferably a crimp connector, connects at least two of the plurality of SMA wires (108) to at least one of the static element and the moveable element.
