Electrical Impedance Spectroscopy techniques have long been used to investigate the frequency dependent electrical properties of biological tissues. Typically termed BioImpedance Spectroscopy, or BIS, these measurements are used in many medical and fitness-related applications. However, many of these measurements suffer from a "hook-artifact", or erroneous increase in reactance at high (f> 500 kHz) frequencies. Existing work models this hook with a stray capacitance in parallel with an existing tissue circuit model. While this model certainly produces a hook artifact, it does not account for the presence of electrodes in the circuit model. This thesis expands on this model to include the impedance of the electrode/tissue interface expected in bioimpedance measurements and include an additional stray capacitance that may exist as a result. This thesis develops the circuit theory to describe the impacts of the electrode/tissue impedance and parasitics in this expanded model. This circuit theory is validated through both simulation and experimental results of the proposed circuit model. From the proposed model, a correction technique to reduce the hook artifact based on measuring both the applied and return currents in a bioimpedance test setup is proposed and explored in simulations.
