  • Patent number: 11760071
    Abstract: An electrically conductive multilayer film is disclosed. The electrically conductive multilayer film may comprise a non-conductive base layer, a transparent layer comprising transparent conductor material, and a transparent primer layer. The non-conductive base layer, the transparent layer comprising transparent conductor material, and the transparent primer layer are arranged one on the other in a vertical direction such that the transparent primer layer is situated between the non-conductive base layer and the transparent layer comprising transparent conductor material and is in direct contact with the transparent layer comprising transparent conductor material. The transparent primer layer is formed of a composition comprising a polymer, wherein the polymer is selected from a group consisting of polyvinylidene chloride, a copolymer, wherein one of the monomers is vinylidene chloride, and any combination thereof. Further is disclosed a method, a touch sensing device, and different uses.

  • Patent number: 11462341
    Abstract: An electrically conductive multilayer film is disclosed. The conductive multilayer film may comprise a non-conductive base layer and a transparent layer comprising transparent conductor material provided on the non-conductive base layer, wherein the transparent layer comprising transparent conductor material is at least partly covered with transparent dielectric material forming a coating layer on the transparent layer comprising transparent conductor material such that the transparent layer comprising transparent conductor material is situated between the coating layer and the non-conductive base layer, and wherein the thickness of the coating layer is 10-600 nm in order to enable processing of the transparent layer comprising transparent conductor material through the coating layer. Further is disclosed a method, a touch sensing device, and different uses.

  • Publication number: 20220195597
    Abstract: Apparatuses and a method for gas phase deposition of high aspect ratio molecular structures, HARM-structures, are presented. The first aspect relates to an apparatus configured for oriented gas phase deposition of HARM-structures on a filter. The second aspect relates to an apparatus configured for oriented gas phase deposition of HARM-structures on a substrate. A system comprising multiple apparatuses according to the second aspect is also presented. Elements of the apparatuses are arranged to create a laminar flow of gas comprising HARM-structures in the deposition area, and to direct this flow at least partially parallel to the deposition area. Another aspect of the invention is a method for oriented deposition of HARM-structures, suitable for deposition both on a filter and a substrate.

  • Publication number: 20090060230
    Abstract: The invention relates to an electromechanical transducer and a method for manufacturing the transducer. The transducer includes a membrane (3), two electrodes (1, 2), the electric field between which can be controlled or measured, and a support structure (4, 5), on which the membrane (3) is arranged to vibrate interactively with the electric field. According to the invention, the support structure (4, 5) includes several support points (4, 5), which are aligned in such a way that several parallel vibrators are formed in the membrane (3).
