Abstract

A miniature camera (1) comprising at least one SMA actuator wire (11) arranged to effect focus, zoom or optical image stabilization. The SMA actuator wire (11) is coated with an electrically insulating layer (40) of thickness in the range from 0.3 μm to 10 μm. The layer (40) provides electrical insulation whilst permitting cooling that provides a rapid response time of the SMA actuator wire (11).
