Motion artefact correction for capacitive ECG measurement

Applications for capacitive ECG measurement that have been demonstrated range from clinical applications like body surface potential mapping to monitoring devices for personal health care. One common drawback in all systems is the susceptibility to motion artefacts caused by relative movement between the capacitive electrodes and the patient. In this paper we describe the setup and experiments that were used to verify the model that simulates time domain behavior of a capacitive electrode. Finally, we show that artefact correction is possible for real world capacitive ECG signals using this model, even for motion artefacts that are within the ECG spectrum.
