The present disclosure relates to a wound electrical component comprising a wound body comprising a plurality of wound layers of a web of an electrically insulating material around a longitudinal axis of the body. The wound body comprises a plurality of electrically conducting layers of an electrically conducting material, each printed onto a respective separate area of the web in the wound body. An edge zone of at least one of the plurality of electrically conducting layers is connected to a printed high permittivity layer of a high permittivity material along said edge zone such that at least a part of the high permittivity layer extends, printed on the web, beyond the edge zone.

Wound electrical component with layers of a high permittivity material

A device for transport of ions and/or charged molecules between a source and a target electrolyte, comprising: a first electrode provided at or in said source electrolyte, and a second electrode provided at or in said target electrolyte; and wherein said first and second electrodes provides an electrical control of an ion flow, and further comprising means for limiting an electronic current between said source and said target electrodes, such that at least after a voltage is applied a potential difference between said source and target electrodes is maintained, which effects ion transport from said source to said target electrode; wherein the device further comprises an ion- and/or permselective polyelectrolyte for transport ions and/or charged molecules via electrophoresis and functions as an ion-selective membrane; and wherein said polyelectrolyte comprises a cross-linked hyperbranched polymer.

Transistor with large ion-complexes in electrolyte layer

In an organic electronic circuit, particularly a memory circuit with an organic ferroelectric or electret material the active material comprises fluorine atoms and consists of various organic materials. The active material is located between a first electrode and a second electrode. A cell with a capacitor-like structure is defined in the active material and can be accessed for an addressing operation via the first and the second electrode. At least one of these electrodes comprises a layer of chemically modified gold. In a passive matrix-addressable electronic device, particularly a ferroelectric or electret memory device, circuits of this kind with the active material as a ferroelectric or electret memory material form the elements of a matrix-addressable array and define the memory cells provided between first and second set of addressing electrodes. At least the electrodes of at least one of the sets then comprise at least a layer of gold. A method in the fabrication of the organic electronic circuit the method comprises steps for depositing a layer of gold as at least one layer of at least one electrode and treating an exposed surface on this layer chemically, whereafter the layer of active material can be deposited on the top of the processed surface of this electrode.

Organic electronic circuit and method for making the same

An organic electronic device consists of one or more electro-active organic or polymer materials sandwiched between electrodes. Critical in such devices is the interface between the electrode and the polymer, where degradation or chemical reaction products may develop that are deleterious to the proper functioning of the device. This is solved by introducing a functional interlayer composed of one or more materials consisting of a molecular backbone bearing phosphonate or phosphate functions, either directly attached or through side chains, said functional layer being disposed between at least one of the respective electrodes and said one or more electro-active materials in the device.
