Abstract: A method for building microstructures, comprising the steps of forming a photopolymer mask on a substrate, having a mask thickness equal to or larger than a desired height of a microstructure to be formed; forming a latent image on the photopolymer mask by exposure to light; applying an electrical charge to the photopolymer mask; developing the cavities in the mask with a functional liquid toner material whose electrical charge polarity is the same as the charge on the mask; and solidifying the functional liquid toner material into a useful microstructure.

Abstract: A backplane having a circuit array having at least one region comprising a substrate having a conductive plane under a dielectric surface, a first conductive layer on said dielectric surface, a selectively disposed insulator disposed over said first conductive layer, and a second conductive layer disposed on said insulator, wherein said first conductive layer is electrically insulated from said second conductive layer, said first conductive layer being formed electrographically, and said second conductive layer being formed by a process comprising selective deposition of liquid droplets, which are then solidified. The second conductive layer may be formed electrographically or by a raster deposition process. The backplane preferably forms an active matrix for a flat panel display using organic semiconductor active elements.

Abstract: A system and method for the manipulation of nanofibers using electrostatic forces. The nanofibers may be provided in a liquid medium, and the nanofibers may be nano-scale (i.e. measured in nanometers). The process is sensitive to the charge properties of the nanofibers (charge could be inherent to material or the charge can be induced into the material through electrochemical means), and therefore may be used to sort or classify particles. The nanofibers may also be aligned according to electrical fields, and thus anisotropic effect exploited. Devices produced may be conductors, semiconductors, active electronic devices, electron emitters, and the like. The nanofibers may be modified after deposition, for example to remove charge-influencing coatings to further enhance their performance, to enhance their adhesion to polymers for use as composite materials or result in the adhesion of the material at the proper location on a variety of different surfaces.

Abstract: A method for applying particles in a pattern to a substrate, either directly or by use of an intermediate tool, by electrokinetic or electrostatic means by exposing the substrate to particles in a fluid medium to electrokinetically or electrostatically deposit the particles onto the substrate.

Abstract: A method and apparatus for the electrostatic printing of dry or wet toners using a novel tiered printing plate allows for superior and efficient transfer of toner from the plate to the printed item. The process for producing the printing plate uses photo polymer film resist with a positive photo tool which after developing yields trenches between ridges of hardened photo polymer which hold the toner in desired pattern.

Abstract: The present invention relates to the fabrication process for the printed wiring boards and flex circuits. An electrostatic printing plate includes a substrate with an image receiving layer applied thereto. The image receiving layer is a toner with a metallic toner and subsequently fixed in place or is transferred to a layer. The metal toner is then fixed on this receiving surface.
