Beschreibung
Zusammenfassung:	Broadly speaking, embodiments of the present techniques provide shape memory alloy (SMA) actuation apparatus for moving a moveable component relative to a static component or support structure and along a notional primary axis. The SMA actuation apparatus may comprise a biasing element to resist motion of the moveable component in particular directions relative to the primary axis, or may comprise an arrangement of SMA actuator wires that provides the biasing function.
