Simulation analysis of equivalent circuit model of skin-electrode impedance for transcutaneous electrical stimulation

For more than 50 years, transcutaneous electrical stimulation method has been used to cure the spinal cord injury, stroke or cerebral palsy. This works by activating excitable nerves, muscle fibers current through electrode skin interface. Electrode interface requires equivalent circuit overcome inability of measuring resistivity directly. We have learned several previous models, which are from Lawler, Moineau and Keller Kuhn. Unfortunately, model neglects capacitance effect, while Lawler Kuhn include capacitive resistive nature in their circuits. Both models consisted only one parallel RC block. Therefore, this paper presents simulation results proposed using two Simulation is conducted MATLAB 2015a compared with certain parameters. Results show that obtained impedance 10.830 kΩ when it simulated 100Hz frequency, for 5.340 6.490 kΩ. The refined other expected deliver better stimulation.
