Abstract

An SMA actuation apparatus () comprising: a plurality of SMA wires (-) arranged, on contraction, to (a) tilt a movable part () relative to a support structure () about a first axis (x) and (b) translationally move the movable part relative to the support structure perpendicular to a primary axis (P); and a control circuit electrically connected to the SMA wires for supplying drive signals thereto, and configured to generate drive signals that combine the tilting and the translational movement to cause the movable element to tilt about a second axis (y) that is perpendicular to the primary axis and spaced from the first axis.
