Magnetically responsive materials are emerging candidates for soft robots and shape-reconfigurable devices. Non-blocked magnetic field from the obstacles between the magnetic source and the target objects provides adaptability for packaged devices. Furthermore, programmable and non-hysteresis magnetic actuations enable multi-modal actuations such as bending, twisting, and their hybridized actuation. In this presentation, we prepared patternable actuation modes within a single sample by adapting patterned magnetic field to align the magnetic component. In addition, we demonstrate the arbitrary patterned actuation of microarray by utilizing a masking technique. Remarkably, reversible and synchronized magnetic actuations of microarrays are demonstrated for performing 100 actuation cycles. The patternable magnetically responsive microarrays could be served as a general platform for shape reconfigurable microdevices. |
