More Information
Summary:A bi-stable sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmold coating, provided about the frame. A resistance-providing component is provided integral with or external to the coated bi-stable sensor such that the bi-stable sensor has two mechanically stable configurations that may be transitioned between by overcoming the resistance provided by the resistance-providing component and/or the by the coating. In one embodiment, the resistance-providing component comprises an elastic band provided about a hinge of the frame, either within or external to the coating. In one embodiment, the sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements.
