Methods, systems, and devices for manufacturing a wearable device are described. Techniques described herein may enable a method for forming one or more dome-shaped protrusions over apertures of a wearable device usable to collect physiological data from a user. For example, a manufacturing process may include adhering a layer of a material with a relatively lower surface energy than metal onto an outer surface of the inner housing of the wearable device prior to dispensing an optically transparent material into the apertures. The optically transparent material may accordingly form the dome-shaped protrusions while in contact with the layer, which may enable the optically transparent material to form relatively higher dome-shaped protrusions as compared to a dome-shaped protrusion formed on a metal material. The layer may be removed following dispensing of the optically transparent material.

Methods, systems, and devices for manufacturing a wearable device are described. Techniques described herein may enable a method for forming one or more dome-shaped protrusions over apertures of a wearable device usable to collect physiological data from a user. For example, a manufacturing process may include forming the dome-shaped protrusions via a channel that connects a first cavity housing a first sensor and a second cavity housing a second sensor. For example, the optically transparent material may be dispensed through a first aperture into the first cavity, may flow via the channel into the second cavity, and may therefore form dome-shaped protrusions through both of the first aperture and a second aperture of the second cavity. The dome-shaped protrusions may accordingly have a same height above a surface of the wearable device.
