SKIN IMPEDANCE AND PHASE ANGLE AS A FUNCTION OF FREQUENCY AND CURRENT

R PLUTCHIK et al. Science. .

Abstract

The impedance of the human skin decreased from approximately 130 to 30 Kohm as the frequency of a-c input increased from 1 to 1000 cycles per second. Over this same range of frequencies, the phase angles changed from -2 to -58 degrees. Changing the peak-to-peak current through the subject from 14 to 62 microamperes had no effect or the phase angles.
