Device for controlling the displacement of a drop between two or several solid substrates
First Claim
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, wherein said reversible displacement includes a phase during which said volume of liquid is not in contact with any solid surface.

18. Method for displacing a volume of liquid having a diameter, 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. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
