ABSTRACT:
The invention relates to a device for displacement of at least a small volume of liquid (5) under the effect of an electrical control, including a substrate (1) provided with first electrically conducting means (2), the device also comprising second electrically conducting means (3) arranged facing the first electrically conducting means (2), the first electrically conducting means and the second electrically conducting means possibly being connected to electrical power supply means to enable the application of electrostatic forces to the small liquid volume (5). The second electrically conducting means include at least one conducting wire (3) arranged parallel to the substrate and at a fixed distance from the substrate to enable displacement of the small volume of liquid (5) along said conducting wire (3) under the effect of the applied electrostatic forces.
