Desktop Tomography System using Planar ECT Device
Abstract: Miniaturized planar
electrical capacitance tomography (ECT) device is fabricated using microfabrication
method to accommodate eight planar electrodes to carry out electrical
capacitancemeasurement using tomography technique. Fluids within the detection
chamber are detected by the difference of the permittivity parameters. Stagnant
and hydrodynamic multiphase samples such as liquidgas and liquid-liquid are
tested. The eight-electrode planar array is fabricated on the copper plated
printed circuit board (PCB) and the chamber is fabricated using polymer poly
(dimethyl-siloxane) (PDMS). The images of the multiphase sample are
reconstructing using Linear Back Projection algorithm (LBP).Computer interface
software is developed to display the images of the fluid online. Experimental
results show that the reconstructed images closely resemble with the
composition of the multiphase sample within the detection chamber.
