More Information
Summary:According to an embodiment of the present invention, a bio signal measuring apparatus may comprise: a pulse wave measuring unit which measures a pulse wave signal of a subject through a plurality of channels; and a processor which analyzes the measured pulse wave signal to determine an oxygen saturation level for each channel, and selects a channel to be used for estimating biometric information among the plurality of channels based on the oxygen saturation level determined for each channel. 일 실시예에 따른 생체 신호 측정 장치는 다수의 채널을 통하여 피검체의 맥파 신호를 측정하는 맥파 측정부와, 상기 측정된 맥파 신호를 분석하여 각 채널별로 산소포화도를 판단하고, 상기 각 채널별로 판단된 산소포화도를 기반으로 상기 다수의 채널 중 생체 정보 추정에 이용될 채널을 선택하는 프로세서를 포함할 수 있다.
