1. A regional oximetry sensor comprising:
a sensor head configured to secure to skin of a user, the sensor head comprising:
an emitter configured to transmit optical radiation into the skin;
at least one detector configured to receive the optical radiation after attenuation by blood flow within the skin;
a first end, a second end opposite the first end, a first side, and a second side opposite the first side, wherein the first end, the second end, the first side, and the second side define a perimeter of the sensor head;
a first plurality of linear channels positioned along a first straight portion of the first side of the perimeter of the sensor head and extending toward an interior of the sensor head; and
a second plurality of linear channels positioned along a second straight portion of the second side of the perimeter of the sensor head and extending toward the interior of the sensor head, wherein the first and second plurality of linear channels form a plurality of independently flexible cutouts in the sensor head configured to allow for movement of at least a portion of the skin of the user underlying the sensor head when the regional oximetry sensor is adhered to the patient, and wherein the first straight portion is non-parallel with respect to the second straight portion; and
a stem extending from the first end of the sensor head and configured to transmit electrical signals from the sensor head to a cable.
