Programmable Microtextures by Programming Magnetic Componenets of Polymer Composites Microarray

초록

Magnetically responsive materials are emerging candidates for untethered shape-reconfigurable devices owing to non-blocked magnetic field from the obstacles which provides adaptability for packaged devices. Furthermore, programmable and non-hysteresis magnetic components enable synchronized actuations. In this presentation, we discuss reconfigurable microtextures capable of on-demand magnetic actuation (bending, twisting, and their hybridized actuation) by engineering the magnetic particle. 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. Furthermore, self-assembly of actuated micropillars results in unique 3D microarchitectures by evaporating a polymer solution.
