The use of commercially available disposable Ag-AgCl electrodes for DC-coupled electro-oculography

Disposable bioelectrically compatible electrodes for direct-coupled electro-oculography have advantages over reusable electrodes in terms of hygiene and convenience. The electrical characteristics of examples of one type of such electrodes were determined. They were found to have suitable noise levels and contact impedance, with acceptable signal drift. They were also found to suppress artefacts on vertical eye movement.
