Abstract

The invention concerns a device for reversibly displacing at least one volume of liquid (10) under the effect of an electrical control, comprising first electrically conductive means (8), second electrically conductive means (4), and means for inducing a reversible displacement of a volume of liquid, from the first to the second electrically conductive means, without contact with said conductive means during the displacement.

Independent Claims | See all claims (29)

1. 1. Device for reversibly displacing at least one volume of liquid under the effect of an electrical control, comprising a first electrical conductor, a second electrical conductor, and means for inducing a reversible displacement of a volume of liquid, from said first to said second electrical conductor, without contact with said electrical conductors during said displacement.
2. 15. Device for reversibly displacing at least one volume of liquid under the effect of an electrical control, comprising a first electrical conductor, a second electrical conductor, and means for inducing a reversible displacement of a volume of liquid, from said first to said second electrical conductor, without contact with said conductors during said displacement, said first electrical conductor being covered with a layer of non wetting or faintly wetting dielectric material and comprising charge transfer means.
3. 16. Method for displacing a volume of liquid, in which said volume is initially in contact with a first substrate comprising a first electrical conductor means, said method comprising: applying a tension between said first electrical conductor and a second substrate comprising a second electrical conductor, and distant from said first substrate by a distance greater than said diameter of said volume of liquid to be displaced, and displacing said volume of liquid from said first substrate to said second substrate, then displacing said volume of liquid from said second substrate to said first substrate.
