ECG measurement without direct conductive contact using chair-mounted electrodes was feasible for obtaining ECGs through several types of clothing compared to conventional Ag-AgCl electrodes.
Does ECG measurement without direct conductive contact on a chair produce comparable signals to conventional Ag-AgCl electrodes?
Non-contact ECG measurement through clothing using chair-mounted electrodes is feasible for everyday monitoring.
For the purpose of long-term, everyday electrocardiogram (ECG) monitoring, we present a convenient method of ECG measurement without direct conductive contact with the skin while subjects sat on a chair wearing normal clothes. Measurements were made using electrodes attached to the back of a chair, high-input-impedance amplifiers mounted on the electrodes, and a large ground-plane placed on the chair seat. ECGs were obtained by the presented method for several types of clothing and compared to ECGs obtained from conventional measurement using Ag-AgCl electrodes. Motion artifacts caused by usual desk works were investigated. This study shows the feasibility of the method for long-term, convenient, everyday use.
Lim et al. (Sat,) conducted a other in ECG monitoring. ECG measurement without direct conductive contact (chair-mounted electrodes) vs. Conventional measurement using Ag-AgCl electrodes was evaluated on Feasibility of obtaining ECGs through clothing and assessment of motion artifacts. ECG measurement without direct conductive contact using chair-mounted electrodes was feasible for obtaining ECGs through several types of clothing compared to conventional Ag-AgCl electrodes.
