An improved Method to continuously monitor the Electrode-Skin Impedance during Bioelectric Measurements. Abstract Text:

Thomas Degen,Teddy Loeliger,Thomas Degen,Teddy Loeliger,

In bioelectric recordings the electrode-skin impedance mismatch reduces the common mode rejection ratio (CMRR) of the amplifier. For this reason, the impedance of each individual electrode-skin contact is usually measured prior to a recording. The measurement circuit itself degrades the CMRR and is switched off during the bioelectric recording. In this work we present a new method that allows to monitor the electrode-skin impedance in a continuous way without reducing the CMRR of the amplifier. The new method is based on an additional common mode signal which is superimposed on the bioelectric signal.
