Abstract
A unitary sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmolded coating provided about the frame. The unitary sensor includes a spring, such as a flat spring or torsion spring, provided on the frame that provides a closing force for the sensor. The sensor may be placed on a patient'"'"'s finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements.
