An improved planar electrode for dielectric parameters extraction

Detection dielectric properties of a biological cell as a function of frequency sweeping is very important, this response can be used to define different information like a chemical, physical or kinetic properties. We analyzed the cell by its conductance and capacitance. This paper presents a numerical study for the capacitance and the conductance based on asymmetric electrodes (AE) configuration compared with a 2D planar electrode are presented. We found the AE configuration improves the sensitivity of the measured capacitance and conductance. Also, a comparison with different cell shapes is simulated using the proposed AE. The simulation shows that there is a difference in a both capacitance and conductance based on the cell shape.
