Externally applied pressure on the skin electrode impedance
The objective of this abstract is to introduce the effects of externally applied pressure on the skin-electrode impedance for electrodes such as standard Ag/AgCl and orbit electrodes. This issue is of interest because it is one of the factors that affect the quality of signal collected from that electrode. Skin-electrode impedance is modeled as an electrical circuit including a resistor (R s ) in series with a paralleled resistor (R d ) and capacitor (C d ). Skin-electrode impedance is measured by an impedance interface device and a frequency response analyzer.
