With a team of over 30 PhDs across data science, engineering, and health science research disciplines, Oura is deeply invested in pioneering research. Our team is involved in more than 130 peer-reviewed publications, each one contributing to the advancement of scientific knowledge in fields such as sleep science, heart rate variability, and activity tracking.
Oura’s commitment to research and innovation spans over a decade. For more than 10 years, we’ve been integrating the latest advancements in both technology and health science into our products. This long-term dedication has led to 14 ongoing collaborations with leading academic and clinical institutes globally, helping us stay at the forefront of health research.
The core of Oura’s success lies in the exceptional accuracy of our sensors. Our smart ring utilizes a range of highly specialized sensors that continuously collect data to monitor your health metrics day and night. These sensors have been meticulously designed to adapt to your unique physiological traits, ensuring that the information you receive is as accurate and personalized as possible.
Our sensors include red and infrared LEDs that measure blood oxygen levels while you sleep, as well as green and infrared LEDs that alternate to measure heart rate and heart rate variability around the clock. The ring also features a negative temperature coefficient (NTC) sensor to track temperature trends and a 3D accelerometer that monitors movement and activity 24/7. These sensors work together to give you comprehensive insights into your health.
The accuracy of Oura Ring’s sensors is unparalleled in the wearable health tech industry. For instance, the heart rate measurement has been validated with an impressive 99% accuracy when compared to ECG readings. Similarly, heart rate variability, an important indicator of overall health, shows 98% accuracy in comparison to ECG data. Additionally, Oura’s ovulation detection technology boasts 94% accuracy when compared to traditional ovulation prediction kits, further enhancing the ring’s utility for women’s health tracking.
Our sleep tracking feature, a key component of Oura’s offering, is also highly accurate, with 79% accuracy when compared to clinical polysomnography, a standard used in sleep studies. This level of accuracy allows users to gain a deeper understanding of their sleep quality, which is critical for optimizing overall health.
The accuracy and reliability of Oura’s sensing technology have been independently validated through numerous peer-reviewed publications, including those featured in prominent journals such as the Journal of Medical Internet Research, Sensors, and Sleep Medicine. These validations reaffirm our dedication to maintaining the highest standards of precision and reliability in all our products.
Oura’s focus on combining advanced technology with rigorous scientific research has made it one of the most accurate and reliable wearables on the market, helping users make informed decisions about their health and well-being.
