Magnetomotility of Magnetic Microrobots in Viscous Solutions |
| 초록 |
Recently, magnetic soft robots have significantly been considered in biomedical applications for untethered control by external magnetic fields. However, Swimming microrobots are affected by drag force in viscous solutions. Herein, we investigate effects of rotational frequency of magnetic fields and solution viscosity on magnetic swimming of magnetic soft microrobots. Hierarchical locomotion of rotation and resultant revolution of microrobots are prompted by perpetual rotation of two linearly connected permanent magnets. Underwater rotation capability of the microrobots is simultaneously determined according to critical value of solution viscosity and rotational magnetic frequency, μf. Also, Underwater orbital revolution is determined by force balance between centrifugal force of the microrobots and magnetic centripetal forces. Furthermore, we will discuss the swimming capability of microrobots in a arteriosclerosis model. |
