Industry-leading accuracy
Sensors
Oura gives you insights into your sleep, activity, and readiness by listening to your body’s signals with three sensors.
Infrared photoplethysmography sensors (PPG) measure heart rate and respiration. PPG is 99% as effective as medical grade equipment.
Negative temperature coefficient (NTC) sensor tracks body temperature. NTC has an accuracy of 92%.
A 3D accelerometer measures movement.
