Abstract
The present invention discloses a smart label to be affixed on or integrated in an object and able to provide an electrical signal indicative of the applied pressure or force and/or the position of the applied pressure or force at a touch point on the object to which the label is affixed. The smart label comprises a layer structure and a detector system, the layer structure comprising of at least a stack of a first, a second and a third layer. The first and third layers comprise a flexible, electrically conductive or semiconductive material and at least two electrodes for connecting the layers to the detector system. The second layer comprises a flexible, deformable and compressible material. The second layer is electrically nonconductive or electrically conductive but less conductive than the first and third layers, wherein the second layer separates the first and third layers.
