Abstract
A method of monitoring the contact of a biomedical electrode to skin of a patient is disclosed, where at least two different frequencies are employed to periodically monitor total contact impedance of the electrode. The ratio of the change of the total contact impedances over time can then be monitored to indicate the amount of lift of the biomedical electrode from human skin to which it is supposed to be adhered. Lift of any portion of the electrode from contact with skin of a patient can be monitored more easily than using conventional Contact Quality Monitoring circuitry and 'split plate patient plates.'
