  • Method for assembling micro structures
    Patent number: 7353593
    Abstract: A method for making three-dimensional structures comprises providing a plurality of components, each of which is moveably coupled to a substrate. The components may be pivotally coupled to the substrate by one or more micromachined hinges. The components are moved using electrostatic forces which lift the components from the surface of the substrate. The components may then be moved further by providing electrostatic forces between components. Two or more components may engage with one another to provide a three-dimensional structure.
    Type: Grant
    Filed: May 9, 2003
    Date of Patent: April 8, 2008
    Assignee: Simon Fraser University
    Inventor: Robert W. Johnstone

  • Method for assembling micro devices and related apparatus
    Publication number: 20030033712
    Abstract: A method for making a three dimensional structure comprises on a substrate providing a plurality of parts hingedly coupled to the substrate; pivoting the parts into positions in which the parts can be inter-engaged by applying electrostatic forces to the parts; and, engaging the parts with one another to provide a three dimensional structure.
