A sensor for pulse oximetry or other applications utilizing spectrophotometry may be adapted to reduce motion artifacts by fixing the optical distance between an emitter and detector. A flexible sensor is provided with a stiffening member to hold the emitter and detector of the sensor in a relatively fixed position when applied to a patient. Further, an annular or partially annular sensor is adapted to hold an emitter and detector of the sensor in a relatively fixed position when applied to a patient. A clip-style sensor is provided with a spacer that controls the distance between the emitter and detector.

1. A sensor comprising: a conformable sensor body comprising an adhesive layer disposed on a tissue-contacting surface, wherein the sensor body is configured to wrap around an end of a patient's digit;a rigid housing disposed on the conformable sensor body on the tissue-contacting surface and configured to directly contact a patient's tissue when in use; andan emitter and a detector embedded in the rigid housing in a reflectance configuration, wherein the rigid housing is adapted to hold the emitter and the detector at a fixed optical distance relative to one another and relative to the patient's digit when the sensor is attached to a patient and when the sensor experiences an external tapping force or when the digit applies a flexing force to the sensor. 2. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a blood constituent sensor or a tissue constituent sensor. 3. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a pulse oximetry sensor or a sensor for measuring a water fraction. 4. The sensor, as set forth in claim 1, wherein the rigid housing is disposed on the sensor body proximate to a midpoint of a longest dimension of the sensor body. 5. The sensor, as set forth in claim 4, wherein the emitter and the detector are disposed along an axis along the longest dimension of the sensor body. 6. The sensor, as set forth in claim 1, wherein the rigid housing is sized and shaped to allow bending of a first joint of the patient's digit when the sensor is applied to the patient. 7. The sensor, as set forth in claim 1, wherein the rigid housing comprises a metal or a rigid polymeric material. 8. The sensor, as set forth in claim 1, comprising an adhesive disposed on a tissue-contacting surface of the rigid housing. 9. The sensor, as set forth in claim 1, wherein both the emitter and the detector are disposed on a same half of the sensor body with respect to an axis approximately orthogonal to a longest dimension of the sensor body. 10. The sensor, as set forth in claim 9, comprising a cable disposed on the same half of the sensor body, coupled to the emitter and the detector, and configured to transmit signals to and from the emitter and the detector. 11. The sensor, as set forth in claim 1, comprising a removable rigid member separate from the rigid housing and disposed within an open cavity in the sensor body. 12. A pulse oximetry system comprising: a pulse oximetry monitor; anda pulse oximetry sensor adapted to be operatively coupled to the monitor, the sensor comprising: a conformable sensor body comprising an adhesive layer disposed on a tissue-contacting surface, wherein the sensor body is configured to wrap around an end of a patient's digit;a rigid housing disposed on the conformable sensor body on the tissue-contacting surface and configured to directly contact a patient's tissue when in use; andan emitter and a detector embedded in the rigid housing in a reflectance configuration, wherein the rigid housing is adapted to hold the emitter and the detector at a fixed optical distance relative to one another and relative to the patient's digit when the sensor is attached to a patient and when the sensor experiences an external tapping force or when the digit applies a flexing force to the sensor. 13. The system, as set forth in claim 12, wherein the sensor comprises a tissue constituent sensor. 14. The system, as set forth in claim 12, wherein the sensor comprises a sensor for measuring a water fraction. 15.
