Abstract :
In this paper a finite element method based model for characterizing the electrode-skin interface is investigated. This electrode model is used to improve the accuracy of the forward solver. The number of elements designed in the interface are large enough to describe these effects about electrode-skin interface. The effect is verified by using the characteristic resistances. From the experimental results, it is shown that this model is in agreement with the physical phantom
