1. An oral appliance, comprising:
a mouthpiece configured to be positioned in an oral cavity of a user, the mouthpiece including:
an anterior wall configured to cover facial surfaces of the user's dentition;
a posterior wall configured to cover lingual surfaces of the user's dentition;
a transverse wall extending between the anterior wall and the posterior wall; and
an electronic assembly coupled to the mouthpiece, the electronic assembly including an oxygen sensor coupled to the anterior wall and configured to be oriented toward oral mucosa of the user's mouth to determine an oxygen saturation level of the user, the oxygen sensor comprising a light emitting diode (LED) and two or more photodiodes (PDs) in an arrangement, the LED configured to project both red and infrared lights, and each of the two or more PDs configured to detect reflections from the oral mucosa of at least a portion of both the red and infrared lights projected by the LED and generate photoplethysmography (PPG) data based on the reflections detected,
wherein the oxygen sensor is configured to detect reflections from the oral mucosa via the arrangement, wherein in the arrangement,
a first PD of the two or more PDs and a second PD of the two or more PDs are positioned on opposite sides of the LED,
a first centerline of the first PD, a second centerline of the second PD, and a third centerline of the LED are positioned in parallel,
the first PD has a major dimension extending along the first centerline and a minor dimension extending perpendicular to the first centerline such that the major dimension is larger than the minor dimension of the first PD,
the second PD has a major dimension extending along the second centerline and a minor dimension extending perpendicular to the second centerline such that the major dimension is larger than the minor dimension of the second PD, and
a distance between the first centerline of the first PD and the second centerline of the second PD is between 6 millimeters and 10 millimeters.
