20.500.12556/RUL-180966 Transfer of energy and momentum between magnetoactive surface microstructure and a solid object Transport systems utilizing magnetic materials are very promising for applications that require contactless operation and compatibility with biological processes. A critical parameter in these systems is the efficiency of energy and momentum transfer between the transporting platform and the objects being transported. We investigate the physical mechanisms driving directional transport of solid objects by microlamellar structures laser-inscribed on the surface of a magnetoactive elastomer (MAE). When subjected to a rotating magnetic field with a magnitude of 175 mT and a time period of 0.4 s, the lamellas reorient within a few milliseconds, reaching angular velocities up to 1100 rad s$^{−1}$. This rapid motion is crucial for efficient momentum and energy transfer to objects in contact with the lamellas. The analysis of collisions of a single lamella with a lead ball with a 2.2 mm diameter shows that the lamella can transfer around 50 nJ of energy, propelling the ball to a speed of around 35 mm s$^{−1}$. We show how this value sets the upper limit for the ball's transport speed on microlamellar structures. We also explain the background of three distinct transport regimes (kicking, pushing, and bouncing modes) observed on these magnetically driven “conveyor belts”. magnetic actuation magnetoactive elastomers object transport surface microstructure magnetoaktivni elastomeri mikrostrukturiranje true false true Angleški jezik Slovenski jezik Članek v reviji 2026-03-20 14:12:19 2026-03-20 14:12:20 2026-03-26 09:04:46 0000-00-00 00:00:00 2026 0 0 9 str. iss. 6, art. no. e202502369 Vol. 28 Mar. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 537.6 1527-2648 10.1002/adem.202502369 267840003 Adv_Eng_Mater_-_2026_-_Geldof_-_Transfer_of_Energy_and_Momentum_Between_Magnetoactive_Surface_Microstructure_and_a_Solid.pdf Adv_Eng_Mater_-_2026_-_Geldof_-_Transfer_of_Energy_and_Momentum_Between_Magnetoactive_Surface_Microstructure_and_a_Solid.pdf 1 3B42F13DA0748F5A9F397C54CE868692 2dd61be70fcae68b32f420d990699690b5b162bd83a5d17b2c116d011b40424a 03e4584c-245f-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231004 https://advanced.onlinelibrary.wiley.com/doi/10.1002/adem.202502369 0 0bd600f0-245f-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231005 https://repozitorij.uni-lj.si/IzpisGradiva.php?id=171495 0 afa6fa8f-245f-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231006 Fakulteta za matematiko in fiziko Fakulteta za strojništvo 0 0 0
