  • Two-axis micro-actuator with multidimensional actuation with large area stage
    Patent number: 7247968
    Abstract: Provided is a two-axis actuator having a large stage area. The two-axis actuator includes a stage moving in two directions and connected to an upper part of an inertial part. The two-axis actuator is configured to maximize a stage area relative to the overall area of the actuator, thereby increasing the data storage capacity of the stage.
    Type: Grant

  • Two-axis actuator with large stage
    Patent number: 7142077
    Abstract: A two-axis actuator having a large stage area and including includes a substrate, an anchor unit having sides approximately in a rectangular shape, fixed on the substrate, a plurality of first actuating parts actuating in a first direction and separated from the substrate within regions of both sides of the anchor unit, a plurality of second actuating parts actuating in a second direction between the first actuating parts, a rectangular shaped stage that actuates in the second direction, disposed above the second actuating parts, a third actuating part formed on the first actuating part, and elevated at a predetermined distance from the stage and the anchor unit, first direction deformable springs that support the first actuating part in inner parts of the anchor unit, and second direction deformable springs formed to fix the second actuating part in an inner part of the third actuating part.
