1. A sensor to aid in diagnosing at least one of infiltration and extravasation in Animalia tissue, the sensor comprising:

  • a housing including—

    a first portion having a surface configured to confront an epidermis of the Animalia tissue; and

    a second portion being coupled with the first portion to generally define an internal volume;

    a set of emission optical fibers being at least partially disposed in the internal volume and configured to transmit a first transcutaneous near infrared signal;

    a set of detection optical fibers being at least partially disposed in the internal volume and configured to transmit a second transcutaneous near infrared signal, the second transcutaneous near infrared signal including a portion of the first transcutaneous near infrared signal that is at least one of reflected, scattered and redirected from perivascular tissue underlying the epidermis; and

    a substantially smooth superficies configured to overlie the epidermis, the superficies including—

    the surface;

    an aggregation of individual emitter end faces of the emission optical fibers, the emitter end faces being configured to emit the first transcutaneous near infrared signal that enters the epidermis; and

    an aggregation of individual detector end faces of the detection optical fibers, the detector end faces being configured to collect the second transcutaneous near infrared signal that exits the epidermis;

    wherein the emitter end faces are disposed in a first band, the individual detector end faces are disposed in a second band, and the first band is generally parallel to the second band.
