Abstract
Method for increasing the ability of at least one droplet to slide over a medium. An ultrasonic surface wave is generated in the medium with a sufficient amplitude to cause the droplet to deform in an inertio-capillary eigen-vibration mode, thus decreasing the attachment of the droplet to the medium, so as to make it easier for the droplet to move under the effect of an external force, the amplitude of the ultrasonic surface wave being insufficient to cause the droplet to deform asymmetrically to the point that it moves in the absence of the external force in the direction of propagation of the ultrasonic surface wave.
