Computer interface and algorithm determines bioelectrode impedance

A computer system for measurement of electrode impedance was developed which permits periodic and automatic determination of proper electrode contact during long-term recording sessions. In addition, the voltage gain of the entire recording system was obtained for subsequent calibration of records....

Zusammenfassung:A computer system for measurement of electrode impedance was developed which permits periodic and automatic determination of proper electrode contact during long-term recording sessions. In addition, the voltage gain of the entire recording system was obtained for subsequent calibration of records. The computer could then record the impedance for documentation or signal the operator for necessary electrode adjustment.
