We are interested in active superhydrophobic materials, whose wetting properties can be tuned with an external parameter.We fabricate soft textured materials and show that the static and dynamic wetting properties of the superhydrophobic materials (such as low liquid-solid adhesion and water-repellency) can be modified either by stretching the substrates or by deflecting them with droplets.We also put into motion superhydrophobic substrates.When deposited on a strongly accelerated non-wetting surface, droplets take unusual and beautiful shapes that we describe and characterize.We finally show that a superhydrophobic streamlined body drags a layer of air when crossing a water/air interface. The thickness of this layer is higher than the heig...
