  • Patent number: 8715478
    Abstract: A device for electrically controlled transport of ions between a source and a target electrolyte, including: a first source electrode and a first target electrode, each capable of conducting ions and electrons, wherein the source electrode is arranged to receive ions from the source electrolyte and the target electrode is arranged to release ions to the target electrolyte.

  • Patent number: 6429457
    Abstract: A field-effect transistor is made with electrodes (2, 4, 5) and isolators (3) in vertically provided layers, such that at least the electrodes (4, 5) and the isolators (3) form a step (6) oriented vertically relative to the first electrode (2) or the substrate (1). Implemented as a junction field-effect transistor (JFET) or a metal-oxide semiconducting field-effect transistor (MOSFET) the electrodes (2, 5) forming respectively the drain and source electrode of the field-effect transistor or vice versa and the electrode (4) the gate electrode of the field-effect transistor. Over the layers in the vertical step (6) an amorphous, polycrystalline or microcrystalline inorganic or organic semiconductor material is provided and forms the active semiconductor of the transistor contacting the gate electrode (8) directly or indirectly and forming a vertically oriented transistor channel (9) of the p or n type between the first (2) and the second (5) electrode.

  • Patent number: 6424553
    Abstract: A device for providing addressability in an apparatus including one or more volume elements which together with the device form part of a matrix in the apparatus. The device establishes an electrical connection to specific cells by electrodes in the matrix and thereby defining a cell in the volume element. The device includes at least three sets of plural strip-like electrodes, the strip-like electrodes of each set being provided in substantially parallel relationship to each other in a two-dimensional and planar layer forming an additional part of the matrix. A set of strip-like electrodes in one layer is oriented at an angle to the projected angle of orientation of the electrode sets in proximal neighboring layers onto this one layer, such that the sets of strip-like electrodes in proximal neighboring layers exhibit a mutual non-orthogonal relationship.

  • Publication number: 20010040828
    Abstract: In a means for providing addressability in an apparatus comprising one or more volume elements which together with said means form part of a matrix in the apparatus and wherein a volume element comprises one or more cells with a data storage or processing functionality, said means establishes an electrical connection to specific cells by means of electrodes in the matrix and thereby defining a cell in the volume element. Said means comprises at least three sets of plural strip-like electrodes, the strip-like electrodes of each set being provided in substantially parallel relationship to each other in a two-dimensional and planar layer forming an additional part of the matrix. A set of strip-like electrodes in one layer is oriented at an angle to the projected angle of orientation of the electrode sets in proximal neighboring layers onto this one layer, such that the sets of strip-like electrodes in proximal neighboring layers exhibit a mutual non-orthogonal relationship.

  • Patent number: 5932965
    Abstract: For providing an electroluminescent device, a first electrode is formed on a substrate that is preferably transparent or translucent, and a first light-emitting layer made of polymeric material is formed on the first electrode and n the substrate. A second light-emitting layer made of polymeric material is formed on a support, preferably stretched together with the support, for orienting the polymeric material thereof, then laminating to the first light-emitting layer and the support is removed. A second electrode is applied on the second light-emitting layer, and the two electrodes are provided with connectors for electrically connecting the device to other structures.
