Dynamic impedance model of the skin-electrode interface for transcutaneous electrical stimulation. [PDF]
PLoS ONE, 2015 Transcutaneous electrical stimulation can depolarize nerve or muscle cells applying impulses through electrodes attached on the skin. For these applications, the electrode-skin impedance is an important factor which influences effectiveness.
