Abstract

In this work, an optical fiber hydrostatic pressure sensor based in Fabry-Perot micro-cavities is presented. These micro structures were generated by the recycling of optical fiber previously damaged by the fiber fuse effect, resulting in a cost effective solution when compared with the traditional methods used to produce similar micro-cavities. The developed sensor was tested for pressures ranging from 20.0 to 190.0 cmH₂O and a sensitivity of 53.7 ± 2.6 pm/cmH₂O for hydrostatic pressures below to 100 cmH₂O was achieved.
