Magnetically responsive materials are emerging candidates for untethered shape-reconfigurable devices owing to penetration of magnetic field through the obstacles, suitable for packaged devices. Furthermore, magnetic actuations of micropillar arrays with soft magnetic systems endow programmable and synchronized actuations by suppressing interference among micropillars. In this presentation, we discuss fabrication method of reconfigurable microtextures capable of on-demand magnetic actuation including bending, twisting, and their hybridized actuation by engineering arrangement of the magnetic particles. In addition, we demonstrate the programming of actuation modes for arbitrary locations of microarray utilizing a masking technique. Remarkably, reversible magnetic actuations of microarrays are demonstrated for performing 100 actuation cycles. Furthermore, we will discuss evaporative self-assembly of magnetically actuated micropillars resulting in unique 3D microarchitectures. |
