Self-propulsion is the autonomous displacement of nano-, micro- and macroscopic natural and artificial objects, containing their own means of motion. Self-propulsion is driven mainly by interfacial phenomena. Various mechanisms of self-propelling have been introduced and investigated, which exploited phoretic effects, gradient surfaces, breaking the wetting symmetry of a droplet on a surface, the Leidenfrost effect, the self-generated hydrodynamic and chemical fields originating from the geometrical confinements, and soluto- and thermo-capillary Marangoni flows. Self-propelled system demonstrate a potential as micro-fluidics devices and micro-mixers. Self-propelled liquid marbles have been demonstrated.

| - La autopropulsión es el desplazamiento autónomo de objetos naturales o artificiales de tamaño nano-, micro- o macroscópico, conteniendo estos sus propios medios de movimiento. La autopropulsión suele estar causada principalmente por fenómenos de interfase. Se han estudiado distintos mecanismos de autopropusión, utilizando efectos foréticos, superficies de gradiente, ruptura de simetrías en superficies, efecto Leidenfrost, campos hidrodinámicos y químicos autogenerados procedentes de confinamientos geométricos, y solutocapilaridad y termocapilaridad en el efecto Marangoni. Los sistemas autopropulsados han mostrado potencial como dispositivos microfluidos y micromezcladores. También se han encontrado autopropulsadas. (es)
