Abstract Stimuli-responsive micropillar structures that can perform dynamics and reversible deformations
according to external stimuli have been applied in a wide spectrum of fields, including object manipulation,
soft miniature robots, and functional surfaces. However, it remains a challenge to exhibit programmable
actuation behaviors for applications that require on-demand deformation response. Herein, a two-step
photomask-assisted template casting technique is developed to fabricate a hybrid magnetic micropillar
array for programmable actuation. By modulating the spatial distribution of the magnetic nanoparticles
within the elastomer micropillars, the bending deformations of the micropillars with different particle
distributions can vary near one order of magnitude under the… More >
