1. A frame of a sensor, comprising:
- a loop structure comprising an emitter housing and a detector housing, wherein the emitter housing and detector housing protrude from an inner surface of the loop structure, and wherein the loop structure is configured to be flexible such that the emitter housing and the detector housing are biased toward one another, and wherein the loop structure is configured to provide support to an overlying coating such that one or more diaphragm structures are formed by the overlying coating.

Abstract
A sensor assembly is provided that includes a frame having a loop structure. An emitter and detector are disposed on opposite sides of the loop structure. A coating is provided over the frame. The coating includes at least one diaphragm structure disposed such that at least one of the emitter and detector can move along an axis running between the emitter and detector. The sensor may thereby be placed on a patient'"'"'s finger, toe, and so forth to obtain pulse oximetry or other physiological measurements. A sensor frame and method of manufacturing the frame are also provided.

7. A pulse oximetry sensor frame, comprising:
a loop structure comprising an emitter housing and a detector housing extending into an interior of the loop structure from opposite sides of an inner surface of the loop structure, wherein the loop structure is configured to be flexible and to bias the emitter housing and the detector housing toward one another, and wherein the loop structure is configured to form a respective diaphragm structure around each of the emitter housing and the detector housing when the loop structures is coated with a coating material. - View Dependent Claims (8, 9, 10, 11)
