Magnetic Micro-Robots

TL;DR

Microrobots controlled by magnetic fields have the potential to revolutionize medicine and drug delivery.

Transcript

These are magnetic microrobots, just millimeters in size. They bend and move in response to applied magnetic fields And with these magnetic fields controlled by a gaming controller the micro robots can be driven carefully and precisely. They can turn by changing the direction of the magnetic field. Roll in a rotating field And even grasp and jump I... Read More

Questions & Answers

Q: How are magnetic microrobots controlled?

Magnetic microrobots are controlled by applying magnetic fields, which allow them to move, turn, roll, grasp, and jump with precision.

Q: What is the potential application of magnetic microrobots in medicine?

Magnetic microrobots could be used in medical applications, such as sending devices into fluid areas of the body or the gastrointestinal tract for sampling or biopsy purposes.

Q: How are magnetic microrobots fabricated?

The fabrication process involves mixing rare earth magnets with UV resin, pouring it into a mold, and using a rotatable permanent magnet to create an adjustable magnetic field for orientation. UV light is then used to cure the resin and lock the magnets in place.

Q: What other potential applications do microrobots have?

Microrobots can be used in drug delivery by carrying small amounts of drugs and being guided towards specific delivery sites. They can also be used for tasks like clearing biofilms on medical devices, pipes, and teeth.
