Magnetic control strategy, device, and applications of the miniature ferrofluidic robot. (IMAGE)
Caption
(A) Conceptual diagram of MFR motion control. (i) Conceptual illustration of MFR directional control based on the horizontal rotation of permanent magnets. (ii) Conceptual illustration of MFR deformation control based on the vertical ascension of permanent magnets. (iii) Conceptual illustration of MFR displacement control based on the translational motion of permanent magnets. (C) Conceptual diagram of detailed components of the magnetic control device. The core components include peripheral coils and a spherical permanent magnet, where the rotation of the permanent magnet is controlled by changing the current in the coils. (D) Conceptual diagram where the MFR drives gear movement through deformation and rotation. (E) Conceptual diagram depicting the MFR driving external devices to deliver objects through deformation and displacement. (F) Conceptual diagram illustrating the MFR-based capsule performing targeted drug delivery.
