In this thesis, we discuss the microstructured surface of a magnetoactive elastomer and its interaction with different objects in an inhomogeneous magnetic field. For a detailed analysis, we have used a high-speed camera in combination with advanced software that allows easy tracking of fast-moving lamellae. We focus on the study of inhomogeneous quadrupole magnetic fields and analyse the responses of individual lamellae and groups of lamellae in such fields. We also study the response velocity of the lamellae, the propagation of the lamellae wave and the inhomogeneous lifting of the lamellae. In addition, we investigate the lamellae-ball collisions, their motion, the restitution coefficient and the variations of the angular momentum, comparing the results obtained with different theoretical models. Special emphasis is given to presenting why such shaped magnetoactive elastomers are particularly suitable for use in lab-on-a-chip devices and self-cleaning surfaces. Finally, we make some suggestions for further research in this area.
