Techniques for adjusting optical paths via angling of optoelectronic components

A wearable ring device, comprising:

• a housing defining an inner surface of the wearable ring device and an outer surface of the wearable ring device, wherein the housing comprises a plurality of apertures within the inner surface of the wearable ring device;
• and
• a printed circuit board disposed within the housing, wherein the printed circuit board wraps at least partially around the wearable ring device within the housing, and wherein a top face of the printed circuit board faces the inner surface of the wearable ring device, the printed circuit board comprising:
• a plurality of optoelectronic components comprising at least a first light emitting component positioned on a first wing of the printed circuit board and at least a first light detecting component;
• wherein the first wing extrudes from a side of the printed circuit board and bends over the top face of the printed circuit board in a first bent position associated with a first angle between a bottom face of the first wing and the top face of the printed circuit board, wherein the first light emitting component is positioned on a top face of the first wing, and wherein a first optical path is defined between the first light emitting component and the first light detecting component based at least in part on the first angle.
