Enhanced magnetic actuation of micropillar arrays with anisotropic geometry effect |
| 초록 |
Reversible and non-destructive magnetic actuation of micropillar arrays was demonstrated by programming chain-like arrangement of magnetic particles. Twisting or bending magnetic response is achieved as particle arrangement axis is offset with external magnetic field axis. Previous studies have actively employed the cylindrical geometry of micropillars where the stiffness distribution is radially balanced within the structure. The actuation degree was attenuated because the momentum cannot be localized. Alternatively, we introduced anisotropic polygonal geometry on magnetic actuation to directionally localize the stress. Rectangular and square form factor was compared by theoretical approach as well as experimental measurements of twisting and bending angle of micropillars. Polar moment of inertia and second moment of inertia are also utilized to analyze the anisotropic stress distribution. |
