Modelling of a 2D magnetic cell transport system

摘要

This paper deals with a magnet cell transport system designed to supply test and treatment modules (e.g. units of a bio-microfactory). Our cell transport system is based on magnetic micro-actuation. Cells are pushed by a ferromagnetic microparticle (diameter 200 μ, thickness 25μ). The motion of the microparticle is performed and controlled by an external magnetic field. In this paper, we present the modelling of the pusher behavior. Our model is composed of a magnetic block (internal magnetic micropusher behaviour), strain block (torque and force applied on the micropusher by the magnet) and dynamic block (dynamic micropusher behaviour). This paper also presents some results like computation of static equilibrium position, comparison with experimental results and size influence study comparison.
