Design of the sample container included voltage sensing electrodes and current driving electrodes for the Kyung Hee University (KHU) Mark2 micro-EIT system. The EIT system injects current on surface electrodes and senses voltages on an additional set of surface electrodes. (a) The dimensions of a sample container and each 3 × 3 current driving electrodes on the current source plane and the current sink plane. (b) 24 × 15 voltage sensing electrodes on three imaging planes and dimensions for each sensing electrode. (c) Simulation of the voltage distributions subject to the primary current ${\mathcal{E}}_{1\pm }$ and (d and e) simulation results for two secondary currents, ${\mathcal{E}}_{2\pm }^1$, ${\mathcal{E}}_{2\pm }^2$.
