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 and (d and e) simulation results for two secondary currents, , .
