DESCRIPTION:Martin Coux\, Engineering Mechanics of Soft lnterfaces EMSI\
 , EPFL\nAbstract  On hard solids\, roughness increases wetting properties
 : hydrophilic substrates become more hydrophilic\, hydrophobic become more
  hydrophobic. Above a critical roughness\, poorly wetting substrates becom
 e almost non-wetting: deposited liquids remain at the top of the textures 
 that cover the solid so that they are actually sitting on a cushion of air
  trapped inside the textures. The substrates are in this case called «sup
 erhydrophobic»\, they exhibit very interesting properties such as water-r
 epellency\, drag reduction\, self-cleaning. In this presentation\, we will
  discuss how the softness of a superhydrophobic substrate can modify its n
 on (poor) wetting properties through three examples.
