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
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. FBGS written in POF fibers will also be used since these fibers can be stretched up to 300% before breaking. This allows them to be used under conditions that would normally result in catastrophic failure of other types of strain sensors.

7. '''Polymers for flexible skinlike materials''' - a series of polymer materials were developed that have inherent flexibility and tuneable mechanical strength. They are also visually transparent and are compatible with commercially available formulations. A great step forward in developing novel monomers and prepolymers that supplement commercial formulations was taken and
8. '''Sensing system for Silica [[Microstructured fiber]]s for pressure and temperature sensing''' - the silica MSF based pressure sensor has great potential value potential in the field of downhole pressure monitoring within the oil and gas industry. In this application there is a need to monitor high pressures (range from 0 to 1000 bar) in combination with fast temperature variations. The ultralow temperature cross-sensitivity is therefore an important feature of this system<ref>http://www.phosfos.eu/eng/Phosfos/Facts-Results/Fact-Sheet-08-Silica-Microstructured-Optical-Fibre-Sensor-Pre-Product-Prototype </ref>
