1. A method for manufacturing a wearable ring device, comprising:
coupling a printed circuit board to an inner ring-shaped housing comprising a plurality of apertures, the inner ring-shaped housing comprising a first metallic material, wherein coupling the printed circuit board to the inner ring-shaped housing comprises aligning a plurality of sensors of the printed circuit board with the plurality of apertures;
coupling an outer ring-shaped housing to the inner ring-shaped housing by at least partially surrounding the inner ring-shaped housing with the outer ring-shaped housing, the outer ring-shaped housing comprising a second metallic material and an additional aperture; and
injecting a filler material through the additional aperture of the outer ring-shaped housing to fill a cavity defined at least in part by the inner ring-shaped housing and the outer ring-shaped housing with the filler material, wherein injecting the filler material comprises filling at least a portion of the plurality of apertures of the inner ring-shaped housing with the filler material.
