Patent ID: 8736139

Claim:
An optical image stabilizer, comprising: a substrate; a table disposed above the substrate, while levitating, to be movable above the substrate and having an image sensor mounted on the table; one or more cantilever arms disposed above the substrate, while levitating, and connected to the table to horizontally move the table; one or more anchors fixing one ends of the one or more cantilever arms to the substrate; and one or more electrodes applying voltage to the respective one or more cantilever arms for horizontally moving the respective one or more cantilever arms without being in contact with the respective one or more cantilever arms and the table, wherein each electrode has a continuously curved surface facing a respective cantilever arm such that a distance between the electrode and the respective cantilever arm is larger at an end of the respective cantilever arm other than the one end fixed to the anchor.
