Abstract
Embodiments disclosed may include a sensor which may be adapted to provide information related to its position on a patient'"'"'s tissue. A sensor may be provided with tissue contact sensors which may relay a signal related to the sensor'"'"'s proper placement adjacent a patient'"'"'s tissue. Such a sensor may be useful for providing information to a clinician about the status of a sensor, such as if a sensor may be located more closely to the tissue in order to provide improved measurements.
