Circuit and method for compensating for an electrode motion artifact
First Claim
1. A method of compensating for an electrode motion artifact, the method comprising:
- measuring an electrocardiogram signal including an electrode motion artifact signal;
forming a first impedance between a subject and a first electrode attached to the subject and forming a second impedance between the subject and a second electrode attached to the subject;
measuring a difference between the first impedance and the second impedance using a carrier signal; and
adjusting the electrocardiogram signal using a signal of the measured difference between the first impedance and the second impedance.

Abstract
A circuit and method for compensating for an electrode motion artifact in which the electrode motion artifact is generated because impedance between a subject and a measuring electrode changes during measurement of the subject'"'"'s biosignal, and the electrode motion artifact can be differentially measured and an electrocardiogram signal can be compensated by introducing a predetermined voltage or an electric current to the subject. A circuit and method for compensating electrode motion artifact, which can differentially measure the difference information between impedance components by introducing a predetermined voltage or electric current to a subject, in association with the electrode motion artifact. In this instance, the impedance component is a component of electrode motion artifact and the electrode motion artifact is generated when measuring a biosignal.
