Abstract:
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.
