Simulation and experiments on magnetic microforces for magnetic microrobots applications [PDF]

2013 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale, 2013
Magnetic microrobots have a wide variety of applications in micro/nano-manipulation, micro/nano sensing and biomedical fields. Untethered magnetic microrobots are usually driven by a group of electromagnetic coils. To control the magnetic microrobots trajectory it is of utmost importance to know the magnitude of the magnetic force applied on them.

Sperm-templated magnetic microrobots [PDF]

2019 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS), 2019
Spermatozoa are efficient microswimmers which perform a bending wave motion for their forward propulsion. By binding positively charged iron oxide microparticles to the surface of negatively charged bull spermatozoa, we fabricate sperm-templated biohybrid magnetic microrobots.

Magnetic microrobots with addressable shape control

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming magnetization in these microrobots that are variant and invariant to folding. The microrobots can
