Performance evaluation of the KHU Mark2 micro-EIT system. (a) The evaluated crosstalk when all switches are in the off-state (case1), when the secondary current flows between ${\mathcal{E}}_{2+}^1$ and ${\mathcal{E}}_{2-}^1$ (case2), and when the secondary current flows between ${\mathcal{E}}_{2+}^2$ and ${\mathcal{E}}_{2-}^2$ (case3). (b) The averaged SNRs of the 15 measurement channels subject to the number of averaged waveform cycles.
