Key result
A noncontact ECG recording system using real-time capacitance measurement and adaptive LMS filtering successfully reduced the severity of certain types of electrode motion artifacts.
A novel noncontact ECG system using real-time capacitance measurement and LMS filtering can successfully reduce electrode motion artifacts.
May support noncontact ECG development; leaves open clinical validation before practice change.
A system for noncontact ECG recording is proposed that measures the real time electrode-body capacitance concurrently with the ECG as a reference signal for motion artifact reduction. Simultaneous recordings of these two signals from the human body in the presence of electrode motion artifacts are shown and an adaptive least-mean-squares (LMS) filtering algorithm run on these signals is demonstrated to be able to reduce the severity of certain types of electrode motion artifacts.
