Abstract
A system is described for the control and measurement of the impedance of electrophysiological surface electrodes which can be used, parallel to the recording of the signal of interest, to determine instantaneously the value of the impedance of the sensor without disturbing the recording. The system works by creating a variation of current and then measuring the variation of the corresponding potential
