Abstract:
1. An apparatus, comprising: a polymeric potting material that encapsulates a fiber optic sensing coil, wherein the fiber optic sensing coil comprises a first coil portion and a second coil portion, wherein the first coil portion is adjacent to the second coil portion, wherein the polymeric potting material comprises a plurality of introduced voids that promote an increase in compressibility of the polymeric potting material, wherein one or more of the plurality of introduced voids are located between the first coil portion and the second coil portion; wherein upon an introduction of an applied force to a portion of the polymeric potting material, one or more of the one or more of the plurality of introduced voids compress to allow the portion of the polymeric potting material to absorb a portion of the applied force and promote a decrease of a reaction force from the portion of the polymeric potting material to the fiber optic sensing coil.
