Mermoud, GFakhfouri, VMartinoli, ABrugger, J2007-06-132007-06-132007https://infoscience.epfl.ch/handle/20.500.14299/7917In this contribution, we describe a novel approach to the problem of setting micrometric droplets in motion. After a short review of the state-of-the-art methods to enable droplet motion, we investigate the scalability of the most promising techniques by using numerical models and systematic experiments. Finally, we propose and evaluate a novel approach based on substrates with radial 3D pattern.text::conference output::conference paper not in proceedings
