Abstract :
Two novel methods are compared for achieving the isolation required to perform high frequency transfer impedance measurements on biological tissue. The first uses sinusoids and the second pulsatile current injection. Sinusoidal current injection offers the higher accuracy but both give similar performance when used to model tissue in terms of a Cole-Cole equation.
