MAGNETIC-DRIVEN SWIMMING MICROROBOTS
Proceedings of the 14th International Workshop on Structural Health Monitoring, 2023A magnetic object subject to an external rotating magnetic field would be rotated due to the alignment tendency between its internal magnetization and the field. Based on this principle, 12 shapes of swimming microrobots around 1mm long were designed and 3Dprinted using biodegradable materials Poly (ethylene glycol) diacrylate (PEDGA).

Magnetically-guided in-situ microrobot fabrication
2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2016Mobile microrobots are typically fabricated in a multi-step microfabrication process and then transported into an enclosed workspace for operation. This paper presents a new, 3D printing inspired method for in-situ fabrication of mobile magnetic microrobots with complex topology from a polymer filament on demand directly inside an enclosed operational ...
