A facile strategy to obtain magnetically actuated arrays of micropillars able to undergo reversible, homogeneous, drastic, and tunable geometrical changes upon application of a magnetic field with variable strength is demonstrated. A magnetically tunable gecko-inspired adhesive that works under dry and wet conditions is realized using elastomeric micropatterns containing magnetic microparticles.
