Abstract
A suspension assembly for a camera lens element includes a support member with a wire attach structure and a moving member coupled to the support member. The moving member includes a plate, flexure arms extending from the plate and coupled to the support member, and a wire attach structure. A bearing supports the plate of the moving member for movement with respect to the support member. The bearing includes a spacer portion extending from one of the support member and the plate of the moving member, and a polymer interface surface portion slidably engaged with the other of the support member and the plate of the moving member. A smart memory alloy wire is coupled to and extends between the wire attach structures of the support member and the moving member.
