The Analysis of Matching Detection Based on Dielectrophoresis Effects
When the effects of dielectrophoresis (DEP) is applied in the detector design, it can be used to detect and locate multi targets.In this paper, the DEP force of neutral objects in the non-uniform electric field is firstly derived.According to analyze the force of insulators in the non-uniform electric field,we can conclude that the mechanical expression of matching detection is DEP force.Then the parameters of DEP force are analyzed and simulated, and it is of great significance to design detector and choose parameters for detector.Finally, through the analysis of the principle of matching detection, the article gives the technology implementation approach of this principle.The results show that this detection method can be used to detect the targets which has the same dielectric material with the detected objects, and it has a strong anti-interference ability.
