The Characterization of Transcutaneous Stimulating Electrodes

A simple mathematical model of a transcutaneous stimulating electrode molded from conductive elastomer is used to predict the current density pattern produced by such electrodes. A general method has been developed to determine experimentally the current distribution produced by this class of electrodes. Preliminary experimental results are qualitatively in agreement with predictions made from the model. The experimental method for the determination of current spread yields a valid assessment of electrode performance independent of the accuracy of the mathematical model.
