Bidirectional droplet motion

Schematic illustration of surface exhibiting bidirectional motion

Description coming soon!

The video below shows the motion of a droplet on a liquid infused surface with a linear topographical gradient.

The next video shows motion of a droplet on a liquid infused surface with a stepwise gradient and negative
driving force.

The final video shows the motion of a droplet on a liquid infused surface with stepwise gradient and positive
driving force.

The videos above are from the Supplementary Information of the publication listed at the end of this page.
