Impedance measurement of individual skin surface electrodes

  • S. Grimnes
Article

Abstract

The methods for the individual determination of skin surface electrode impedances are briefly discussed. A measurement technique is described with which it is possible to measure two skin surface electrodes simultaneously, but individually, at the same frequency. The design of a small, portable, battery-operated meter using this principle is described with block diagrams. Results are presented from the study of bilateral g.s.r. waves, the site dependence of the skin impedance, the differences between 10Hz and 1000 Hz data, and tissue segment impedance.
