Escape dynamics of liquid droplets confined between soft interfaces: non-inertial coalescence cascades

We have studied the motion of liquid droplets located in the contact zone of two soft solids that are pressed together inside a liquid. The driving force of the motion is the gradient of elastic contact pressure. Upon reaching the perimeter of the contact spot, the droplets coalesce with the surroun...
