Brinnae Bent and Jessilyn Dunn form Duke University wrote an article about wearable technology. Wearable technology has the potential to transform healthcare and research through accessible, continuous, and longitudinal health monitoring.
The accuracy of wearable technologies has been a hotly debated topic both in research and in popular culture. As wearable technologies are increasingly being used for clinical research and healthcare, it is critical to understand their accuracy and determine how measurement errors may affect research conclusions and impact healthcare decision-making.
Further, the type of physical activity going on during a measurement also plays an important role in the accuracy of the heart rate measurement: we saw an approximate 30% drop in accuracy when a person is walking versus when they are seated at rest
In a study, the authors tested optical heart rate sensors on six of the most popular devices on the market for both consumers (Apple Watch, Fitbit, Garmin, XiaoMi Miband) and for research (Empatica E4, Biovotion Everion) against the clinical reference standard for monitoring heart rate, the electrocardiogram (ECG).
