Water droplet friction and rolling dynamics on superhydrophobic surfaces

Hydrophobic coatings are increasingly important in modern technology, but hard to study in the extreme non-wetting limit. Here, micropipette force sensors can directly measure nN-scale friction forces and, combined with particle image velocimetry, reveal pure rolling dynamics of slow water droplets.
