Abstract

A wristband-type PPG heart rate sensor capable of overcoming motion artifacts in daily activity and detecting heart rate variability has been developed together with a motion artifact cancellation framework. In this work, a motion artifact model in daily life was derived and motion artifacts caused by activity of arm, finger, and wrist were cancelled significantly. Highly reliable instant heart rate detection with high noise-resistance was achieved from noise-reduced pulse signals based on peak-detection and autocorrelation methods. The wristband-type PPG heart rate sensor with our motion artifact cancellation framework was compared with ECG instant heart rate measurement in both laboratory and office environments. In a laboratory environment, mean reliability (percentage of time within 10% error relative to ECG instant heart rate) was 86.5% and the one-day pulse-accuracy achievement rate based on time use data of body motions in daily life was 88.1% or approximately 21 hours. Our device and motion artifact cancellation framework enable continuous heart rate variability monitoring in daily life and could be applied to heart rate variability analysis and emotion recognition.
