A wearable ring device, comprising:

• a ring-shaped housing comprising one or more carbon fiber layers, the ring-shaped housing configured to at least partially surround a finger of a user;
• one or more electronic components embedded within, or attached to, the one or more carbon fiber layers of the ring-shaped housing, the one or more electronic components comprising one or more light-emitting components, one or more light-receiving components, and one or more radio frequency transceiver components;
• a battery electrically coupled with the one or more electronic components;
• and
• one or more processors configured to:
• acquire physiological data associated with the user based at least in part on light transmitted via the one or more light-emitting components and received by the one or more light-receiving components;
• and
• transmit the physiological data to a user device via the one or more radio frequency transceiver components.
