INSULATION OF COMPONENTS OF AN SMA ACTUATION ARRANGEMENT IN A MINIATURE CAMERA

摘要

Insulation of components of an SMA actuation arrangement in a miniature camera A miniature camera comprises an SMA actuator arrangement including at least one SMA actuator wire arranged to effect focus, zoom or optical image stabilization. At least one component of the SMA actuator arrangement that is not the SMA actuator wireis coated with an electrically insulating layer, thereby reducing the risk of short circuiting of the drive current of the SMA actuator wire. The SMA actuator wire may not be coated at all.
