While the conductive gel achieves the requirement in making a good contact between the electrodes and skin, several problems appear. A gel-free, non-contact electrode based on capacitive coupling theory was provided in this paper, which was integrated on the print circuit board (PCB). The experimental results showed that clear ECG signals could be acquired in the laboratory conditions by coupling the electrodes to the chest of patients through cotton belts.展开更多
