The PHOSFOS (Photonic Skins For Optical Sensing) project<ref>http://www.phosfos.eu/eng/Phosfos/About-us/Project-Summary </ref> is developing flexible and stretchable foils or skins that integrate optical sensing elements with optical and electrical devices as well as onboard signal processing and wireless communications, as seen in Figure 1. This flexible skins can be wrapped around, embedded in, attached and anchored to irregularly shaped and/or moving objects or bodies and will allow quasi-distributed sensing of mechanical quantities such as deformation, pressure, stress or strain<ref>http://spie.org/x38859.xml?highlight=x2406&ArticleID=x38859</ref>. This approach potentially gives a significant advnatage over conventional sensing systems because of the portability of the resulting systems and the extended measurement range.
The sensing technology is based around sensing elements called [[Fiber Bragg Grating]]s (FBGs) that are fabricated in standard single core silica fibers, highly birefringent [[Microstructured fiber]]s (MSF) and [[Plastic optical fiber]]s (POF). The silica MSFs are designed to exhibit almost zero temperature sensitivity to cope with the traditional temperature cross-sensitivity issues of conventional fiber sensors. These specialty fibers are being modeled, designed, fabricated within the programme.
Once optimized the sensors are embedded into the sensing skin and on the interfaced to the peripheral optoelectronics and electronics. These skins are really flexible, see Figure 2.
