1. A forehead sensor configured to output signals responsive to physiological parameters of a wearer thereof, the forehead sensor comprising:
- a reflectance-type oximetry sensor including a light source and at least one light detector configured to output a signal responsive to attenuation of reflected light from said light source;
at least one electrode pair including a first and second electrode; and
an attachment mechanism, said attachment mechanism configured to be worn on a front of a forehead of a wearer and position the light source and detector in a first measurement area on the forehead, and position the electrode pair in a second measurement area on the forehead, said first measurement area not divided by said second measurement area between said position of said light source and said position of said detector, said oximetry sensor configured to monitor said first measurement area and said electrode pair configured to monitor said second measurement area.

Abstract
A physiological sensor combination has a flexible substrate configured to attach to a tissue site. Multiple sensors are disposed on the substrate, which generate physiological signals. Each of the signals is responsive to a different physiological parameter. Conductors are carried on the substrate and routed between the sensors and at least one connector. The connector is configured to communicate the physiological signals to at least one monitor, which derives measurements of the parameters.

4. A sensor adapted to a forehead of a patient, the sensor including an optical sensor and an electrode sensor, the sensor comprising:
-
the optical sensor configured to output an optical sensor signal responsive to attenuation of reflected light from said light source, said attenuation caused by tissue at a first measurement site; the electrode sensor including at least one electrode pair, the electrode sensor configured to output an electrode sensor signal responsive to electrical signals at a second measurement site; and adhesive attachment tape including one or more portions, the tape configured to be worn on a forehead of the patient and position the optical sensor and the electrode sensor, wherein said first measurement site is not divided by said second measurement site between said position of said optical sensor and said position of said electrode sensor.
