摘要：
PURPOSE: An apparatus and method for measuring a bioelectric signal are provided to accurately measure the bioelectric signal of a subject by extracting and removing a motion artifact included in the bioelectric signal due to the motion of the subject.CONSTITUTION: A first interface(120,140) detects a bioelectric signal of a subject(110) through electric interfacing with the skin of the subject. A second interface(130,150) detects another signal through an electric interfacing which is different from the electric interfacing of the first interface. A signal processing unit(180) removes a motion artifact between the first interface and the skin from the detected bioelectric signal and includes a motion artifact extracting unit(160) and a bioelectric signal extracting unit(170). The motion artifact extracting unit extracts a signal in proportion to the motion artifact using the detected signal from the second interface. The bioelectric signal extracting unit removes the motion artifact from the detected bioelectric signal by using the extracted signal from the motion artifact extracting unit.COPYRIGHT KIPO 2013[Reference numerals] (160) Motion artifact extracting unit (170) Bioelectric signal extracting unit (AA) Bioelectric signal생체 신호를 측정하는 생체 신호 측정 장치 및 이를 수행하는 방법에 따르면, 생체 신호 측정 장치는 낮은 접촉 임피던스를 갖는 전극을 이용하여 생체 신호를 검출하고, 높은 접촉 임피던스를 갖는 전극, 즉 임피던스 변화와 동잡음과의 상관 관계가 높은 전극을 이용하여 전위 신호를 검출한다. 검출된 전위 신호로부터 동잡음에 비례하는 신호를 획득하고, 이를 검출된 생체 신호로부터 제거하여 동잡음이 제거된 정확한 생체 신호를 획득한다.
