Development of the Non-contact ECG Electrode

We designed a non-contact electrode on the basis of the capacitance coupling principle, it can be used for physiological signal acquisition, it uses dynamic shielding and electrode active driving technology to improve the quality of the signal. Experiments use this electrode to structure the ECG signal acquisition system, the ECG signal were collected with non-contact electrodes, comparing with traditional wet electrodes, the results show that noncontact electrodes developed in this paper can effectively meet the needs of ECG signal acquisition.
