This thesis primarily focuses on the propulsion mechanism behind the 3D-printed colloidal microswimmers in liquid crystals, which are driven by an applied alternating electric field. The first results chapter demonstrates the influence of the aspect ratio of polymer microrods on their propulsion vel ...

We use polarized optical microscopy and confocal fluorescence microscopy to explore electric-field induced swimming of direct laser written polymer microrods in a nematic liquid crystal in the regime of very low frequencies. The rods are of variable aspect ratio and swim in a liquid crystal layer wi ...
