Embodiments of the disclosed technique disclose an optical device generating light by luminescence comprising a substrate, a waveguide, a pump light source and a photoluminescent layer, wherein the waveguide is positioned between the substrate and the photoluminescent layer, or the photoluminescent layer is positioned between the substrate and the waveguide. The pump light source is provided opposite to the photoluminescent layer at the backside of the substrate. The pump light source is adapted to pump the photoluminescent layer to emit light; and at least some of the emitted light is evanescently coupled into the waveguide.

Light coupling device and system, and method for manufacturing the device and system

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.
