An SMA haptic assembly comprises relatively movable first and second parts and a length of SMA wire, the ends of which are connected to the first part or second part, wherein the first and second parts comprise at least one contact portion making contact with the length of SMA wire on opposite sides of the length of SMA wire and relatively positioned so as to guide the length of SMA wire along a tortuous path such that the first and second parts are driven in opposite directions along a movement axis on contraction of the length of SMA wire. The at least one contact portion of one or both of the first and second parts is formed from sheet material that is shaped to guide the path of the SMA wire in contact therewith, thereby reducing the overall thickness and simplifying manufacture.
