1. A sensor comprising:
- a fabric or woven stocking cap;
a gripping portion disposed in a band region of the stocking cap comprising a tissue-contacting surface;
an emitter disposed on the gripping portion, wherein the emitter is configured to emit a light into a forehead region of the patient'"'"'s head;
a detector disposed on the gripping portion, wherein the detector is configured to detect the light;
a first lead coupled to the emitter;
a second lead coupled to the detector; and
a cable extending from an opening in a top portion of the stocking cap and terminating in the band region, wherein the cable is coupled to the first lead and the second lead at a point spaced apart from the gripping portion.
