RESEARCH-GRADE SENSORS
Oura Ring is powered by sensors that adapt to
your unique physiology — delivering accurate,
continuous data, day and night.
>Red and infrared LEDs measure blood oxygen levels
while you sleep
>Green and infrared LEDs alternate to measure heart
rate and heart rate variability 24/7 and respiration
rate during sleep
>Negative temperature coefficient (NTC) sensor
tracks temperature trends
>3D Accelerometer tracks movement and activity
24/7
Independently
validated sensors
Oura Ring's sensing capabilities have been independently validated in several peer-reviewed publications, including the Journal of Medical Internet Research, Sensors, and Sleep Medicine.
