Model Establishment of Microfluidic Chip in Form of Planar Coil for Metal Particles Detection
Base on electromagnetism and consideration of Eddy Current within the particles, the magnetization models of ferromagnetic metallic and non-ferromagnetic metallic particles are established in harmonic field.Combined with Electromagnetics model of the linear planar coil, relative inductance changes caused by particles pass is got in AC current.And the planar coils sensitivity to particles after different relative permeability of particles, size of particles, parameters of planar coil and distance between particles and planar coil are discussed.The experiments test was carried out to various sizes of particles.The test indicated that Sensitivity can be improved by increase planar coils intensity, decreasing the distance of detection.
