Finite Element Analysis for Yeast Cells using Electrical Capacitance Tomography Most of the biomedical imaging technologies are immobile, bulky, expansive, and required specialized staff for maintenance. These disadvantages led to many research in electrical tomography technique with its advantages and features such as smallscale device, lowcost, mobile and easy fabrication. This paper aims to explore the feasibility of electrical capacitance tomography (ECT) to detect permittivity of yeast cell through modeling and simulation using COMSOL Multiphysics. The electrical conductivity of yeast increase as the growth of yeast increases, therefore an ECT model is designed to capture the electrical parameter from the membrane of the yeast cell thus detecting its permittivity distribution in a yeast extract peptone dextrose medium. The obtained Maxwell capacitance voltage result is presented in this paper. The study shows that ECT model with 8 electrode pairs is able to detect the yeast cell or Saccharomyces cerevisiae growth up to a diameter size of 5 to 10  mu mathrmm .

Simulation Study of TwoPhase Fluid 3D Imaging Using LabonChip ECT Electrical Capacitance Tomography (ECT) is a popular technique for multiphase fluidic imaging. For the sake of better microfluidics handling within a miniaturized platform, this paper presents a simulation study of a labonchip 3D ECT model with two set of 8planarelectrode arrays position circularly on the top and bottom layer of the sensing microchamber. The presented simulation studies are to reconstruct the 3D images of a square phantom (water) in a background (air) with different location by using Linear Backward Propagation (LBP) as the image reconstruction algorithm. The simulation results have shown that the proposed labonchip 3D ECT is capable to identify the different position of the phantom.
