Agile Hierarchical Swimming of Soft Microrobots in Viscous Glycerol Solutions

초록

Magnetically responsive microrobots allow path programming in confined or blocked environments, facilitating actuation in diminutive blood vessel-like systems. Recently, we demonstrated agile hierarchical motility of soft microrobots capable of rotation and revolution by rotating linearly connected two permanent magnets. In this presentation, we will analyze underwater swimming behaviors of the magnetic soft robots in viscous glycerol?water solutions to affect the hierarchical motility and swimming velocity. Furthermore, we will demonstrate swimmability of the soft microrobots in arteriosclerosis-like environments.
