1. A sensor, comprising:

  • a conformable sensor body having a tissue-contact surface;

    an emitter and detector disposed on the tissue-contact surface in a reflectance configuration; and

    a deformable element disposed on the sensor body on a surface opposing the emitter and the detector, wherein the deformable element comprises a material having a deformation point, and wherein the deformable element is configured to cause a portion of the sensor body to protrude against a patient'"'"'s tissue when the sensor is applied to the patient'"'"'s tissue and when a force is applied to the deformable element that exceeds the deformation point of the material such that the pressure applied by the sensor body is non-uniform across the tissue-contact surface and is highest in the area of the sensor body proximate to the emitter and the detector.
