1. A system comprising:
- a sensor body;
an emitter and a detector disposed adjacent the sensor body; and
a tissue contact sensor disposed adjacent the sensor body, wherein the tissue contact sensor comprises a temperature sensor configured to measure a temperature; and
a processor coupled to the tissue contact sensor configured to determine whether the sensor is on a tissue of a patient based, at least in part, on the measured temperature.

Abstract
In an embodiment, a sensor may be adapted to provide information related to its position on a patient'"'"'s tissue. The sensor may include tissue contact sensors which may relay a signal related to the proper placement of the sensor relative to the tissue of a patient. Such a sensor may be useful for providing information to a clinician regarding the location of the sensor in relation to the skin of a patient in order to provide improved measurements.

15. A method, comprising:
-
measuring, with a first temperature sensor disposed on a tissue contacting surface of a pulse oximetry sensor, a first temperature; measuring, with a second temperature sensor disposed on a non-tissue contacting surface of the pulse oximetry sensor, a second temperature; determining, with a processor, a difference between the first and second temperatures; and determining, with the processor, whether the pulse oximetry sensor is on a tissue of a patient based, at least in part, on the difference between the first and second temperatures. - View Dependent Claims (16, 17, 18, 19, 20)
