The directed propulsion of small scale objects in water is
problematic because of the combination of low Reynolds number and
Brownian motion on these length scales. One possibility for designing
propulsion is to devise non-reciprocal deformation strategies that
are simple enough to be realizable. Another strategy could be to take
advantage of various phoretic phenomena. In this seminar, a number of
simple models from each category will be introduced and the experimental
realization of one of these devices at Sheffield and another one in Barcelona
will be reported together with the quantitative analysis of the
observed motion.
