Design of the KHU Mark2 micro-EIT system. (a) Implemented KHU Mark2 micro-EIT system, and (b) its functional block diagram. The system connects to a PC over USB. The digital backplane controls the current source, each measurement channel and organizes data acquisition. Each channel contains a voltmeter that is connected to the analog backplane. These are connected to the sample container through a switch network and associated controller.
