A Strain‐engineered Helical Structure as a Self‐adaptive Magnetic Microswimmer
ChemNanoMat, 2021AbstractInspired by flagellar bacteria, helical microswimmers are proposed in many biomedical applications due to their efficient propulsion at low Reynolds numbers. And the ability to swim through a confined environment such as a blood capillary is an urgent issue to further expand their functions both in vivo and in vitro.

Closed-loop 3D path following of scaled-up helical microswimmers
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016This paper addresses the problem of 3D path following of magnetic helical microswimmers in closed-loop. An error kinematic model in a local frame with sideslip and attack angles is used to express the motion of the helical microswimmer. A new derivation of the chained form with three inputs and five states is used to linearize the kinematic model in ...
