Beschreibung
Zusammenfassung:	An SMA haptic assembly comprising: a length of SMA wire; and first and second parts that are movable relative to each other along a movement axis, the length of SMA wire being connected at each end to a respective support portion which is a portion of the first or second part; wherein each of the first and second parts comprises at least one contact portion and a connection portion which connects the at least one contact portion and any support portion of the respective one of the first and second parts; wherein the at least one contact portion of the first part and the at least one contact portion of the second part are relatively positioned so as to make contact with the length of SMA wire on opposite sides of the length of SMA wire along the movement axis and to guide the length of SMA wire along a tortuous path such that the first and second parts are driven apart along the movement axis on contraction of the length of SMA wire; and wherein the connection portion of the first body is a beam disposed on a side of the length of SMA wire in a direction normal to the movement axis.
