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.
