Abstract
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 stabilize 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 vapor sensor can also be achieved.
