Abstract
A device for forming at least one circulating flow, or vortex, at the surface of a drop of liquid, including at least two first electrodes forming a plane and having edges facing each other, such that the contact line of a drop, deposited on the device and fixed relatively to the device, has a tangent forming, when projected onto the plane of the electrodes, an angle between 0° and 90° with the edges facing each other of the electrodes.

31. A device for forming at least one circulating flow, or vortex, at the surface of a drop of liquid, comprising:
-
at least two first electrodes forming a plane and having edges facing each other, such that the contact line of a drop, deposited on the device and fixed relatively to the device, has a tangent forming, when projected onto the plane of the electrodes, an angle between 0° and
90°
with the edges facing each other of the electrodes; anda potential generating device allowing application between the two first electrodes of a potential difference which gives rise to an oblique electric field. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A method for forming at least one circulating flow or vortex in a drop of liquid, or at its surface, in a surrounding medium, having relatively to each other different dielectric properties and/or different resistivities, comprising:
-
positioning the drop on a device including at least two first electrodes having edges facing each other, so that the projection of the contact line of the drop on the plane containing the electrodes has a tangent forming with these electrode edges an angle between 0° and
90°
; andapplying an electric field between the two electrodes, the drop being fixed relatively to the device. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
