Abstract :
The electrode system is one of the most sensitive and crucial parts in EIT system. In this paper, a method for EIT electrode structure and parameter optimizing design, took example for compound electrode, has been presented, which is based on the coercive equipotential node model of line electrode. A simulation research software platform for electrode structure and parameter optimizing design has also been developed. By the method, the varieties influences of electrode structure and parameters on reconstructed image and measure sensitivity can be obtained. This will provide theory basis for the electrode structure optimum design of real EIT system
