PulseOn is a wrist-worn optical heart rate (HR) monitor based on photoplethysmography. It utilizes multi-wavelength technology and optimized sensor geometry to monitor blood flow at different depths of skin tissue, and it dynamically adapts to an optimal measurement depth in different conditions. Movement artefacts are reduced by adaptive movement-cancellation algorithms and optimized mechanics, which stabilize the sensor-to-skin contact. In this paper, we evaluated the accuracy and reliability of PulseOn technology against ECG-derived HR in laboratory conditions during a wide range of physical activities and also during outdoor sports. In addition, we compared the performance to another on-the-shelf wrist-worn consumer product Mio LINK(®). The results showed PulseOn reliability (% of time with error <;10bpm) of 94.5% with accuracy (100% - mean absolute percentage error) 96.6% as compared to ECG (vs 86.6% and 94.4% for Mio LINK(®), correspondingly) during laboratory protocol. Similar or better reliability and accuracy was seen during normal outdoor sports activities. The results show that PulseOn provides reliability and accuracy similar to traditional chest strap ECG HR monitors during cardiovascular exercise.
PulseOn是一款基于光电容积脉搏波描记法的腕戴式光学心率监测器。它采用多波长技术和优化的传感器几何结构，以监测皮肤组织不同深度的血流，并能在不同条件下动态适应最佳测量深度。通过自适应运动消除算法和优化的机械结构减少运动伪影，从而稳定传感器与皮肤的接触。在本文中，我们在实验室条件下，针对多种体育活动以及户外运动，评估了PulseOn技术相对于心电图衍生心率的准确性和可靠性。此外，我们还将其性能与另一款市售腕戴式消费产品Mio LINK(®)进行了比较。结果显示，在实验室测试中，与心电图相比，PulseOn的可靠性（误差<10bpm的时间百分比）为94.5%，准确性（100% - 平均绝对百分比误差）为96.6%（而Mio LINK(®)相应为86.6%和94.4%）。在正常户外运动中也观察到了相似或更好的可靠性和准确性。结果表明，在心血管运动期间，PulseOn提供的可靠性和准确性与传统胸带式心电图心率监测器相似。
