1. A sensor comprising:
- a conformable bandage-type sensor body adapted to be directly applied to a patient'"'"'s digit;
at least one sensing element disposed on the sensor body on a tissue-contacting surface; and
at least one rigid annular structure not fixedly attached to the sensor body and adapted to be applied to the sensor body on a surface opposing the tissue-contacting surface with a pressure to retain the sensor body in place on the patient'"'"'s digit and such that the rigid annular structure covers an area of the sensor body corresponding to the at least one sensing element and covers less than 50% of the surface of the sensor body when the sensor is applied to the patient.

Abstract
A sensor may be adapted to reduce signal artifacts by deflecting the effects of outside forces and sensor motion. A sensor is provided with a rigid annular structure adapted to reduce the effect of motion of a sensor emitter and/or detector. Further, a method of deflecting or minimizing outside forces and sensor motion is also provided.
