Enhancing Swimming Performance of Magnetic Helical Microswimmers by Surface Microstructure
LangmuirArtificial bacterial flagella (ABF), also known as a magnetic helical microswimmer, has demonstrated enormous potential in various future biomedical applications (e.g., targeted drug delivery and minimally invasive surgery). Nevertheless, when used for in vivo/in vitro treatment applications, it is essential to achieve the high motion efficiency of the

Multi-flagella helical microswimmers for multiscale cargo transport and reversible targeted binding
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015In-vivo and in-vitro micro-interventions by mobile robotic agents require their precise control. Numerous types of microrobotic swimmers have been developed, assuming different peculiar applications, but often suffering from a lack of mobility and robustness, due to their unique propulsion mode. Hence we present in this paper the multi-flagella helical

Design and Analysis of a Helically Propelled Microswimmer
Theoretical and Natural ScienceBacteria can navigate through microscopic environments, which are highly viscous. The secret of their movement lies in the flagella on the body. These flagella spin in a spiral way in the fluid to propel the body forward. This provides the scientists an efficient strategy for propulsion under low Reynolds number.

Magnetic helical microswimmers in poiseuille flow
2014We analyze the motion of artificial magnetic microswimmers which mimic the swimming of natural organisms at low Reynolds numbers. Artificial magnetic microswimmers consist of a rigidly connected helical tail and a magnetic head. Magnetic swimmers are actuated with three orthogonal electromagnetic coil pairs.

Trajectories of artificial microswimmers with helical tails inside circular channels [PDF]
, 2016 Trajectories are obtained for millimeter-scale artificial microswimmers inside circular channels filled with glycerol. Rotating magnetic field is applied to propel 3D-printed swimmers with helical tails and permanent magnetic heads. Experiments are recorded with a high-speed camera and processed with contrast-based image processing tools to extract 3D ...

This short communication presents a simple microswimmer model with a stiff spherical head and a flexible helical springtail for non-Newtonian fluid propulsion at low Reynolds numbers. A closed-form velocity equation was created by modeling the tail as a linear spring under viscous drag with isolated dynamics.
