Oura Ring

Summary

Oura Ring is a multi-sensor wearable worn on the finger as opposed to the wrist. It uses machine learning algorithms to determine sleep and wake from multiple sensors measuring pulse, body temperature, and motion.

Claimed Capabilities/Measurements

Oura Ring provides users with three Oura scores – sleep, readiness and activity. It also claims to track night-time ECG-level resting heart rate (RHR), interbeat interval (IBI) and heart rate variability (HRV); sleep stages (deep, REM, light), sleep timing, duration and quality; respiratory rate, breathing variance; thermometer-level body temperature deviation; movements and daily rhythms; intensity, timing and length of physical activities; inactivity and sedentary time including alerts. Oura Ring also claims to use data to help users with in-depth sleep improvement programs and personalized circadian alignment guidance.

Mechanism

Oura Ring measures pulse, interbeat interval (IBI), heart rate variability (HRV), respiratory rate, breathing variance, body temperature, and motion.

Sensors

Oura Ring uses infrared photoplethysmography (PPG), a body temperature sensor, 3D accelerometer, and gyroscope.

Technical Considerations

Data is uploaded to the Oura Cloud. Data is also synced to the Oura mobile application.
