Impedance spectroscopy has been proved to be a useful technique for analyzing heterogeneous systems, especially biological cell suspensions and tissues because of its capacity of non-invasive measurement. In the present paper, experiments were conducted to study the dielectric properties of yeast cells by Impedance Spectroscopy. The capacitance of the suspension of yeast cells was measured and the...
This paper simulates the electrical particle concentration and migration in the small diameter particles in a micro-channel using CFD. This research is a first step to visualize, concentrate and distribute particles behavior at certain cross-section and between cross section under capacitance sensing. The calculation conditions are Reynolds number influence of electrical power, and cross-section,...
Monitoring of thrombogenic process is very important in ventricular assistance devices (VADs) used as temporary or permanent measures in patients with advanced heart failure. Currently, there is a lack of a system which can perform a real-time monitoring of thrombogenic activity. Electrical signals vary according to the change in concentration of coagulation factors as well as the distribution of...
This paper shows a result of simulations of the particle behavior at particle-liquid two phase flow via dielectrophoresis varied the number of electrodes by using COMSOL. Dielectrophoresis is very important technique to study tomography at micro-scale. The calculation parameters are Reynolds number, voltage and volume fraction, Particles volume fraction is the same in the each cases. As a result,...
