Bidirectional actuation of ferrofluid using micropatterned planar coils assisted by bias magnetic fields
This paper reports a ferrofluid control method that enables both attraction and repelling of ferrofluid on micropatterned planar coils coupled with permanent magnets. A combinational use of a controlled magnetic field and a bias field is shown to provide lateral forces that attract/repel the ferrofl...
