Asymmetric sensors for ring wearable

A wearable device, comprising:

• a first light-emitting component configured to emit light within at least a first wavelength range, the first light-emitting component positioned within an inner curved surface of the wearable device at a first radial position in a first direction relative to an axis of the wearable device, wherein the axis defines a radial midpoint of the wearable device;
• a second light-emitting component configured to emit light within at least the first wavelength range, the second light-emitting component positioned within the inner curved surface of the wearable device at a second radial position in a second direction, opposite the first direction, relative to the axis of the wearable device, wherein the first radial position and the second radial position define a segment of the inner curved surface between the first radial position and the second radial position, and wherein the first radial position and the second radial position are symmetrical across the axis;
• a first photodetector configured to receive light emitted by the first light-emitting component via a first optical path associated with a first threshold penetration depth and the second light-emitting component via a second optical path associated with a second threshold penetration depth, different than the first threshold penetration depth, the first photodetector positioned at a third radial position within the segment of the inner curved surface between the first radial position and the second radial position, wherein the third radial position is offset from the axis such that a first radial distance between the first photodetector and the first light-emitting component is greater than a second radial distance between the first photodetector and the second light-emitting component such that the third radial position is asymmetrical across the axis, wherein no additional light-emitting components are positioned between the first photodetector and the first light-emitting component and between the first photodetector and the second light-emitting component;
• a second photodetector configured to receive light emitted by the first light-emitting component via a third optical path associated with the second threshold penetration depth and the second light-emitting component via a fourth optical path associated with the first threshold penetration depth, the second photodetector positioned at a fourth radial position outside of the segment of the inner curved surface, wherein the fourth radial position is offset from the axis by a third radial distance and in the first direction;
• and
• a third photodetector configured to receive light emitted by the first light-emitting component via a fifth optical path associated with the first threshold penetration depth and the second light-emitting component via a sixth optical path associated with the second threshold penetration depth, the third photodetector positioned at a fifth radial position outside of the segment of the inner curved surface, wherein the fifth radial position is offset from the axis by the third radial distance and in the second direction such that the fourth radial position and the fifth radial position are symmetrical across the axis, wherein the first threshold penetration depth is associated with measurement of a first type of physiological data and the second threshold penetration depth is associated with measurement of a second type of physiological data, different than the first type of physiological data.
