“…For several years, smart textiles have been a fast-growing development and there has been an increasing market for these materials. In these textiles, optical fibers can be integrated as sensors for various applications [1], for instance as monitoring of structures in civil engineering [2], seat occupancy in automotive industry [3,4,5], and position analysis [6,7]. However, these textiles are particularly interesting in the field of medical textiles.…”

The objective of this paper is to study the ability of polymer optical fiber (POF) to be inserted in a knitted fabric and to measure both pressure and friction when walking. Firstly, POF, marketed and in development, have been compared in terms of the required mechanical properties for the insertion of the fiber directly into a knitted fabric on an industrial scale, i.e. elongation, bending rigidity, and minimum bending radius before plastic deformation. Secondly, the chosen optical fiber was inserted inside several types of knitted fabric and was shown to be sensitive to friction and compression. The knitted structure with the highest sensitivity has been chosen for sock prototype manufacturing. Finally, a feasibility study with an instrumented sock showed that it is possible to detect the different phases of walking in terms of compression and friction.

“…Similarly, seat‐occupancy can be monitored with POFs . The response of POFs to bending and axial tension was investigated, and while the sensitivity to bending is essential for this application, the materials also have to show appropriate elasticity to withstand cyclic loading and to return to a base value …”

Polymer optical fibres are increasingly being used for medical applications, e.g. as wearable devices for diagnostics or therapeutics. Due to the multitude of applications and the corresponding restrictions and prerequisites, the properties of these optical fibres are fine-tuned to their specific application. Regarding wearables and continuous, unobtrusive long-term monitoring, a very low burden is reached when the integration into textiles is complete and the wearer's comfort is ensured. Here, we discuss a selection of recent solutions within wearable photonic sensors. Integration processes are highlighted so as to provide insight for further development. Finally, implications of long-term monitoring are discussed including data mining. The effect of knowing one's vitals on society is highlighted as a relevant influence on medical care. If ubiquitous monitoring were realized for a high percentage of the population, concerns can arise regarding the long-term reliability of photonic sensors as well as ethical use of patient data.
