Heart rate (HR) sensing during exercise is essential for medical, healthcare and sport physiological purposes. Photo-Plethysmo-Graphy (PPG) is a simple and non-invasive technique for HR sensing, but it is highly sensitive to motion artifact. This paper proposes a cancellation technique of motion artifact in PPG-based HR sensing for a man during exercise. The canceller is equipped with two sensors; one is a normal PPG sensor where an LED/Photo-Detector (PD) contacts the skin to detect Blood Volume Pulse (BVP) (+motion artifact) and the other is a motion artifact sensor where an LED/PD does not contact the skin to detect only motion artifact. Experimental results show that the proposed technique, which is implemented in adaptive algorithms, can sense HR correctly by cancelling motion artifact induced by exercises such as running and jumping.
运动过程中的心率（HR）监测对于医学、医疗保健和运动生理学目的至关重要。光电容积脉搏波描记法（PPG）是一种用于心率监测的简单且非侵入性的技术，但它对运动伪影高度敏感。本文提出了一种针对运动中男性基于PPG的心率监测的运动伪影消除技术。该消除器配备有两个传感器；一个是普通的PPG传感器，其中发光二极管/光电探测器（LED/PD）与皮肤接触以检测血容量脉搏（BVP）（+运动伪影），另一个是运动伪影传感器，其中LED/PD不与皮肤接触仅检测运动伪影。实验结果表明，通过自适应算法实现的所提出技术能够通过消除跑步和跳跃等运动引起的运动伪影来正确地监测心率。
