Abstract
A shape memory alloy (SMA) actuator () for a camera assembly, comprising:—a support structure supporting an electronic component, wherein the electronic component is susceptible to interference caused by magnetic flux; —a moveable part moveable relative to the support structure; one or more SMA components () connected between the moveable part and the support structure, wherein the one or more SMA components are configured to, on contraction, drive movement of the movable part; —a first electrical path and a second electrical path defined between, and/or including, each of the one or more SMA components () and respective electrical terminals (a); and wherein the first and second electrical paths of each of the one or more SMA components are configured to, at least in part, extend adjacently to and in parallel with each other, and enabling the electrical current in the respective paths to flow in opposite directions, so as to minimise combined magnetic flux from the first and second electrical paths into the electronic component.
