Shape memory alloy actuator arrangement
First Claim
1. A shape memory alloy actuator arrangement for a camera lens assembly, the shape memory alloy actuator arrangement comprising:
- a support structure;
a movable element for supporting a camera lens assembly comprising at least one lens having an optical axis;
plural shape memory alloy actuator wires connected between the support structure and the movable element in an arrangement wherein the shape memory alloy actuator wires are arranged, on selective driving, to move the movable element relative to the support structure in any direction orthogonal to the optical axis; and
at least one plain bearing that bears the movable element on the support structure, allowing movement of the movable element relative to the support structure orthogonal to the optical axis.

Abstract
A shape memory alloy actuator arrangement for a movable element supporting a camera lens assembly comprises plural shape memory alloy actuator wires connected between a support structure and the movable element in an arrangement wherein the shape memory alloy actuator wires are arranged, on selective driving, to move the movable element relative to the support structure in any direction orthogonal to the optical axis of the at least one lens. At least one plain bearing bears the movable element on the support structure, allowing movement of the movable element relative to the support structure orthogonal to the optical axis.
