Abstract:

Arrays of transcutaneous electrode elements have been proposed as a method to improve selective muscle stimulation and functional control. Measuring the current distribution across the surface of these electrode elements is important for understanding how the electric field penetrates into human tissue. A new measurement system has been developed that simulates human skin at the electrode interface. Small structures were incorporated, allowing localised changes in skin impedance to be simulated. Current flow through the measurement system was recorded and used to produce current distribution maps at the simulated electrode skin interface. First measurements indicated that coupling gel helped to uniformly distribute stimulation current across the surface of the electrode. Simulating localised changes in skin impedance produced large current densities and non-uniform current distributions, which is in agreement with published literature.
