Abstract: In this paper we report the successful development of pressure sensitive textile
prototypes based on flexible optical fibers technology. Our approach is based on
thermoplastic silicone fibers, which can be integrated into woven textiles. As soon as
pressure at a certain area of the textile is applied to these fibers they change their cross
section reversibly, due to their elastomeric character, and a simultaneous change in
transmitted light intensity can be detected. We have successfully manufactured two
different woven samples with fibers of 0.51 and 0.98 mm diameter in warp and weft
direction, fo
