Patent number: 11618186Abstract: The invention relates to a method for forming an article comprising a pathway of particles wherein a termination of the pathway of particles is exposed. The method comprises arranging the particles by applying an electric field and/or a magnetic field at an interface between a water soluble or a non-water soluble matrix and a matrix comprising a viscous material and particles. After fixating the viscous material, the termination is exposed by dissolving the water soluble or non-water soluble matrix. The invention also relates to articles obtainable by said method, and to the use of said method in various applications.Type: GrantFiled: July 9, 2021Date of Patent: April 4, 2023Assignee: CONDALIGN ASInventors: Robert F. Praino, Jr., Denise A. Radkowski, Henrik Hemmen

Publication number: 20200245514Abstract: A layer of the mixture that contains polymer and conductive particles is applied over a first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the layer. An electric field is applied over the layer, so that a number of the conductive particles are aligned with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilise the layer. This leads to a stable layer with enhanced and anisotropic conductivity.Type: ApplicationFiled: August 29, 2019Publication date: July 30, 2020Applicant: CONDALIGN ASInventors: Eldrid SVASAND, Mark BUCHANAN, Matti KNAAPILA, Geir HELGESEN

Publication number: 20180312392Abstract: A sensor is achieved by applying a layer of a mixture that contains polymer and conductive particles over a substrate or first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the material. An electric field is applied over the layer, so that a number of the conductive particles are assembled into one or more chain-like conductive pathways with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilise the material. The conductivity of the pathway is highly sensitive to the deformations and it can therefore act as deformation sensor. The pathways can be transparent and is thus suited for conductive and resistive touch screens. Other sensors such as strain gauge and vapour sensor can also be achieved.Type: ApplicationFiled: July 9, 2018Publication date: November 1, 2018Applicant: CONDALIGN ASInventors: Mark BUCHANAN, Matti KNAAPILA, Geir HELGESEN, Henrik HOEYER
