✦ Synopsis

A water droplet placed on a vibrating surface moves toward the antinode of the vibration. The acoustic radiation pressure can explain this non-linear phenomenon. In this paper, the use of a piezoelectric actuator to produce a displacement of liquid droplets is pointed out. Due to geometry of the actuator and the position of piezoelectric ceramics, it is possible to generate stationary modes in the structure where the nodal lines can move.

Various experiments have been performed to study the interaction of a liquid layer and vibrating plates. A liquid layer deposited on a vibrating plate exhibits a deformation of the surface with a high amplitude of vibration (larger than 1 m at 30 kHz). Furthermore, a water droplet placed on the vibr
