Abstract

The micropump has a displacement unit displacing a drop (51) of liquid (L1) by electrowetting on a hydrophobic surface till the drop is contacted with a hydrophilic wall (12) of a microchannel (10) such that the drop is introduced by wetting in the microchannel through an inlet orifice (11) to cause displacement of fluid (F1). The displacement unit has displacement electrodes (31) and a counter-electrode provided in electrical contact with the drop. The drop forms a contact angle on the hydrophilic wall, where the angle is less than an angle formed by electrowetting on the surface.
