    摘要: The invention relates to a micropump for which the pressure force is not limited by the electrowetting saturation angle, while being simple to manufacture. According to the invention, the microchannel (10) comprises an inlet orifice (11) and has a hydrophilic wall (12) extending from said inlet orifice (11). Displacement means are provided to displace a droplet (51) of liquid (L1) by electrowetting on a hydrophobic surface (22) until said droplet (51) is brought into contact with said hydrophilic wall (12), such that said droplet (51) enters into said microchannel (10) through said inlet orifice (11) by wetting, causing displacement of said fluid (F1).
