The magnetomechanical actuation of micropillars is developed for the contactless manipulation of miniaturized actuators and microtextured surfaces. Anisotropic geometry of micropillars can significantly enhance the magnetic actuation compared with their isotropic counterparts by directional stress distributions. However, this strategy is not viable for triangular micropillars owing to insufficient...
Magnetomechanical Actuation
In article number 2305272, Hyoung Jin Choi, Jeong Jae Wie, and co‐workers report enhanced magnetomechanical actuation of micropillars with hard magnetic nanorod/soft magnetic microsphere composite particles. This hybridization arouses a synergy of magnetic couplings and structural percolation, improving magnetization and storage modulus of the composites.
