1. A sensor fiber comprising:
- An elongated, unsupported three-dimensional fiber body comprising an electrically insulating polymeric material, the fiber body having a fiber length and an outer fiber body surface along the fiber length, with at least one intake aperture disposed in the fiber body for accepting an intake species into the fiber body;
at least one transduction element comprising a chemiluminescent material disposed within the fiber body along at least a portion of the to fiber length and arranged for exposure to an intake species provided through an intake aperture in the fiber body, the chemiluminescent material emitting chemiluminescent light upon exposure to a target intake species with a wavelength of chemiluminescence indicative of the target intake species;
at least one photoconducting element comprising a semiconducting material arranged in the fiber body in optical communication with the transduction element to receive chemiluminescent light produced by the chemiluminescent material upon reaction of the chemiluminescent material with the target species to produce a corresponding electrical sensing signal indicative of the target intake species; and
at least one pair of electrically conducting electrodes in electrical connection with the photoconducting element in the fiber body, the pair of electrodes extending the fiber length to transmit the electrical sensing signal to an end of the fiber body.

Abstract
There is provided a sensor fiber including an electrically insulating material having a fiber length. At least one transduction element is disposed along at least a portion of the fiber length and is arranged for exposure to an intake species. A photoconducting element is in optical communication with the transduction element. At least one pair of electrically conducting electrodes are in electrical connection with the photoconducting element. The pair of electrodes extend the fiber length.
