  • Publication number: 20050236260
    Abstract: Micro-electromechanical devices having an improved flexible layer enable the use of material having a wider range of elastic modulus. The MEM devices include a substantially non-pliable layer and a substantially flexible layer both of which include electrodes that when energized will create electrostatic forces that attracts the flexible layer to the non-pliable layer. The flexible layer has perforations or apertures cut into the flexible layer of a MEMs device to alter operational properties such as electrostatic sensitivity, resonance frequency, rate of change of sensitivity above the resonance frequency, oscillating mass, panel stiffness and others parameters.

  • Publication number: 20050134644
    Abstract: The present invention relates to a printer system that incorporates an electrically addressable array of micro electro-mechanical switches of arbitrary width. In one embodiment, array of micro electro-mechanical switches of arbitrary width that comprises an electrostatic array used to attract fusible toner or electrically charged ink droplets from a hopper or ink jet assembly to a piece of paper or other printable substrate. The electrostatic array uses electrostatic latching to create the charged environment to allow the toner or ink to be attracted from the hopper or ink jet assembly toward the array. A piece of paper is interposed between the array and the hopper or ink jet assembly. Additional micro electro-mechanical switches control the release of the ink droplets from the ink jet assembly. The micro electro-mechanical switches each comprise a sealed cell that relies on pneumatic restoration forces to insure that switch contacts can be successfully broken as desired.

  • Publication number: 20050116924
    Abstract: A low cost, scalable backplane for black and white or color optical displays comprises a multi-membrane plastic structure on which is printed or deposited row and column drivers to form a matrix of micro electromechanical (MEM) switches. Each switch controls the state of a pixel in the optical display device. Critical to successful long-term operation, the backplane includes the controlled application of voltages to each switch so that the display functions correctly and display life is maximized. The MEM switches include a substantially non-pliable membrane and a substantially flexible membrane both of which include electrodes that when energized will create electrostatic forces that attracts the flexible membrane to the non-pliable membrane. The MEM switches are manufactured in an array with a pitch that provides a sufficient number of switches to drive an optical display device and each switch may be latched to eliminate the need to constantly refresh the device.
