Insulator and conductive analysis material via Electrical Impedance Tomography

The characterization of conductive and insulator materials plays an essential role in biomedical engineering. A technique is to measure the difference in conductivity of the domain and compare it with a reference material. The present work analyzes the resistivity difference between a copper and PVC tube. The data acquisition was obtained by the LatePanda device integrated into an Arduino board coupled to a phantom of 16 electrodes located on the periphery. Electrical Impedance Tomography (EIT) was used to measure the resistivity changes. The images showed a significant difference between conductive and insulating material. The obtained information from the test will be used in future works to determine the varying of resistivity amongst a healthy and one cancer tissue.
