1. A sensor comprising:

  • an emitter and a detector coupled to a substantially rigid substrate, the substrate being disposed on a tissue-contacting surface of a bandage-type sensor body configured to extend over a digit, wherein the substantially rigid substrate is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient, and wherein the bandage-type sensor body comprises sufficient elastic material to accommodate digit movement within the sensor.
