Apparatus and method for measuring a biological signal

摘要

Provided is a method and apparatuses for measuring a biological signal, in which a biological signal of an examinee is detected via at least one interface that touches skin of the examinee, and a dummy signal is detected via a dummy interface. Noise that is generated by a fluctuation in the electrical characteristics of the at least one interface is removed from the biological signal using the biological signal and the dummy signal.
