Abstract :	[en] In this thesis, we discuss some physical phenomena related to the manipulation of droplets, and their possible use as alternatives for digital microfluidics. In a first part, the behavior of droplets in the vicinity of another liquid interface is explored. We have shown that droplets can be kept bouncing onto a liquid interface, provided this latter is vertically vibrated. The bouncing mechanisms are investigated in several configurations. Bouncing droplets may also experience self-propulsion and partial coalescence. The second part of this thesis is dedicated to the study of droplets sliding down fibers. The basic microfluidic operations are advantageously implemented with simple fiber networks.
