Uses of water-shedding surfaces
Here we show examples of self-propelled droplet motion induced by gradients in surface texture or hydrophobicity.
Self-propelled
Droplet Motion

Long-distance motion of droplets along complex paths can be designed using tapered slippery microrails.
Bidirectional Droplet
Motion

A droplet on tapered slippery microrails separated by a liquid lubricant may move either forwards or backwards.
