Description

A neonatal heartbeat detection method using doppler sensor has been proposed. The method removes respiration waveform from the measured signal with template matching method synchronizing at each respiration period. The proportion of heartbeat to respiration rate of neonate decreases of 58% compared to adult, and desired effects of current frequrncy analyses will not be enough. The proposed method calculates heartbeat interval directly without frequency analyses, and measurements are stable even when the proportion is small. Through the experiments of the neonatal model which can simulate respiration and heartbet, and of an adult, we show that the measurement errors are 0.0-3.3%.
