Technical textiles with embedded fibre optic sensors habe been developed for the purposes of the structural health monitoring in geotechnical and civil engineering as well as for healthcare monitoring in the medical sector. The paper shows selected examples of using such sensor-based smart textiles for different applications.
The versatility of MPOF offers a variety of sensing applications. In this paper the influence
of strain, temperature and humidity is investigated. The results show that MPOF LPGs are well suited
for strain sensing. Further investigations have to be made to clarify the behaviour on temperature and
humidity in more detail.
We investigate two real-time strain sensing principles based on the optical time-domain reflectometry
(OTDR) in polymer optical fibres (POF). The first sensing principle uses the increase of the level of backscattered light
in a stretched POF. The second sensing principle uses the effect of losses due to bending.
