A Micro Diamagnetic Actuator for Micro Beads Levitation and Manipulation

Abstract:

Article Preview

An efficient and convenient way to levitate and manipulate micro beads is reported, in which coils and soft magnetic materials are used to generate a magnetic field. The levitation is based on diamagnetic buoyancy, and the main structure of this device is made into spiral switch arrays so as to simplify the interconnection and magnetic field control. The design, modeling and fabrication of the device for manipulation of diamagnetic beads is given in detail. Theoretic analysis and experimental results of fabrication indicate the advantages and feasibility of the proposal illustrated here.
