The Electric Field Analysis of Interdigitated Electrode-Array Based on Semi-Analytical Method

Abstract:

Dielectrophoresis (DEP) is the action of polarizable particles in non-uniform electric field, which depends on the structure of electrode. In this paper, we present a semi-analytical method, on which the electric field distribution by interdigitated electrode-array with battlement structure is considered. According to the congregational conformation of latex micro-beads which subject to the negative dielectrophoresis movement, the potential-trap by interdigitated electrodes is observed experimentally. The result shows that the theoretical simulation result conforms to actual electric field distribution well. It is proved that semi-analytical method exerts power for the research of dielectrophoresis effectively.
