Abstract:
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.
