This work concerns the design of microsystems for the travelling of liquid droplets under an electric field. The driving electrodes laid on glass are scaled at some tens of µm. The achieved demonstrators allow basic manipulation : cutting of a droplet from an inlet reservoir and its transporting over a few electrode network but also joining two droplets. Finally the concept of dielectrophoretic transport is examined in view to handle conducting biological liquids which can recover a dielectric behaviour under a high frequency electric field.
