Apparatus and Method for High-Speed Determination of Bioelectric Electrode Impedances <back to top>


Abstract: Apparatuses and methods are provided for determining electrode impedances of a bioelectric signal-monitoring/recording system that includes an amplifier, and electrodes connected between a subject and the amplifier. An example apparatus includes: a voltage source outputting a voltage signal; a switching arrangement including an input electrically connected with the voltage source for receiving the voltage signal, an output electrically connected with the amplifier and the electrodes, and switches between the input and the output; and a controller in communication with the switches for opening and closing the switches to establish signal paths between the voltage source and the output, the controller calculating the electrode impedances relative to voltage outputs of the amplifier for each signal path.
