Abstract
Methods and apparatus for surface wetting control are disclosed. In certain described examples, an apparatus can expel fluid from a droplet on a surface using a transducer mechanically coupled to the surface. A first area of the surface can have a first wettability for the fluid, and a second area of the surface can have a second wettability for the fluid. The first wettability of the first area of the surface can be greater than the second wettability of the second area of the surface. The first area and the second area can be arranged in a patterned arrangement.
