1. A sensor comprising:
- a sensor body configured to be applied to a patient'"'"'s digit comprising at least one elastic electronic component disposed on the sensor body; and
an emitter and a detector disposed on the sensor body, wherein the at least one elastic electronic component and the sensor body are adapted to expand in response to a bending movement of the digit and maintain a substantially fixed optical distance between the emitter and the detector.

Abstract
A sensor may be adapted to reduce motion artifacts by mitigating the effects of the tissue moving within the sensor. A sensor is provided with an elastic sensor body adapted to accommodate patient motion. Further, a sensor is provided in which the sensor cable is arranged to mitigate its pressure on a patient'"'"'s tissue.
