Gas sensors based on optical fibers are attractive alternatives to the presently available sensors. Integration of sensor fibers into protective clothing would significantly increase sensor wearability. We present a gas sensing polymer optical fiber (POF) that is flexible enough to be stitched into textiles. Also, the polymer is UV-transparent to allow for fluorescent dyes. By using a porous sol-gel matrix, response times down to 1 s were achieved.
