A fully flexible and stretchable planar waveguide serving as a photoluminescent concentrator, fabricated from a mixture of PDMS with a fluorescence dye, can be used to detect localized light. The incident light is absorbed by the dye, leading to an emission of light with higher wavelength. The emitted light is spreading out in the two dimensional waveguide and detected via embedded Si-photodiodes in the device. Using a simple mathematical model, the position of light spots can then be easily recalculated. These devices can lead to applications, such as human interface devices and artificial skins.
