基于手机内置多传感器的瞬时心率估计
Instantaneous heart rate estimation based on the built-in multisensor of an Android smartphone
摘要
Abstract
This paper presents a novel method for instantaneous heart rate estimation(IHRE)because of the diffi-culty in estimating by pulse wave signals captured by smartphone cameras.In this method,the Android camera and accelerometer sensors are used in conjunction.The camera collects the photoplethysmography(PPG)signals of a body,and the accelerometer sensor,built into the smartphone,calculates the respiratory wave signals of the abdo-men,which are taken as the carrier signals.The variable frequency complex demodulation(VFCCM)demodulates PPG signals to obtain the instantaneous heart rate signals.When compared with traditional short-term autocorrela-tion(STA)method,the error of the efficiency of the IHRE method was decreased by 14.3%and the accuracy rate was increased by 11.5%,using the traditional EGG method as a reference.Therefore, in Android smartphones, the IHRE method can effectively and accurately estimate the instantaneous heart rate.关键词
