Abstract
The invention relates to a method for pumping through an orifice (30, 31) of a first substrate (1), a first volume of liquid (2) in contact with a first hydrophobic surface of said substrate, wherein a pressure variation between the first volume of liquid and a second volume of liquid (2′), located in contact with said orifice and a second hydrophobic surface of said substrate, is achieved by electrowetting.
Claims17
An apparatus comprising:
- a substrate, having a first and a second surface, at least one of which is hydrophobic or covered with a hydrophobic layer, and at least one orifice crossing through said substrates;
- means for displacing, by electrowetting, a volume of liquid on one of said faces of the substrate through said orifice;
- and
- first and second electrodes configured to be in direct contact with the volume of liquid as the volume of liquid is displaced through said orifice, to be controlled by a computer, and to supply said computer with data regarding a variation of an electric characteristic of the volume of liquid as the volume of liquid is displaced through said orifice.
