Abstract: A method of fluid manipulation involves applying electric signals at one or more electrodes located on or adjacent to a surface in contact with a liquid that contains a surfactant. The electric field generated by the electric signals (e.g., biasing voltage) applied to the electrodes makes the liquid less wetting on the surface than the natural state and can be used to move or modify the shape of the liquid droplet placed on the surface. One embodiment makes a liquid dewet locally on a surface by applying electric signals locally on the surface so that the liquid can be electrically manipulated on a hydrophilic surface.
