Abstract
The displacement of a fluid is controlled electrically in a device employed primarily for storage and display of digital data. The device comprises a capillary space delimited by two confinement plates, the internal faces of which are fitted with electrodes connected to an electric generator. The capillary space is shared by two immiscible fluids and at least one displaceable fluid marker is created within the capillary space in the form of a globule of the fluid which has the highest dielectric permittivity.
