摘要

我们开发了一种基于光电容积脉搏波(PPG)的心率(HR)传感器[1]，它配备了两个传感器;一个是普通的PPG传感器，另一个是运动伪影传感器。在基于ppg的HR传感器中，对两个传感器的输出采用自适应滤波算法，可以有效地消除剧烈运动引起的运动伪影。在基于ppg的HR传感中，呼吸运动也是伪影的主要来源之一。在本文中，我们对基于ppg的HR传感器对呼吸运动伪影的抵消性能进行了评价。

Breathing motion artifact cancellation in PPG-based heart rate sensing

We have developed a photoplethysmography (PPG)-based heart rate (HR) sensor [1], which is equipped with two sensors; one is a normal PPG sensor and the other is a motion artifact sensor. In the PPG-based HR sensor, applying an adaptive filter algorithm for the outputs from the two sensors, it can effectively cancel motion artifact induced by vigorous exercise. Breathing motion is also one of the main sources of artifact in PPG-based HR sensing. In this paper, we evaluate the cancellation performance of breathing motion artifact by the PPG-based HR sensor in experiments using five subjects.
