20.500.12556/RUL-168613 Control of droplet impact through magnetic actuation of surface microstructures An effective method for on-demand control over the impact dynamics of droplets on a magnetoresponsive surface is reported. The surface is comprised of micrometer-sized lamellas from a magnetoactive elastomer on a copper substrate. The surface itself is fabricated using laser micromachining. The orientation of the lamellae is switched from edge-on (orthogonal to the surface) to face-on (parallel to the surface) by changing the direction of a moderate (<250 mT) magnetic field. This simple actuation technique can significantly change the critical velocities of droplet rebound, deposition, and splashing. Rebound and deposition regimes can be switched up to Weber number We < 13 ± 3, while deposition and splashing can be switched in the range of 32 < We < 52. Because a permanent magnet is used, no permanent power supply is required for maintaining the particular regime of droplet impact. The presented technology is highly flexible and enables selective fabrication and actuation of microstructures on complex devices. It has great potential for applications in soft robotics, microfluidics, and advanced thermal management. magnetoactive elastomers laser micromachining wettability magnetoaktivni elastomeri lasersko strukturiranje omočljivost true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-18 10:08:26 2025-04-18 10:08:27 2025-04-19 04:37:03 0000-00-00 00:00:00 2023 0 0 10 str. art. 2202471 Vol. 10 Apr. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.3 2196-7350 10.1002/admi.202202471 145255427 Jezersek_..._-_Control_of_Droplet.pdf Jezersek_..._-_Control_of_Droplet.pdf 1 BA3257F6F2CE349EE9E34593928ED76B 8d3668034037d3eb51f59f0b453859cd033671756723a2e23ca415734c2f0186 d2b2d642-1c2b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209493 https://advanced.onlinelibrary.wiley.com/doi/10.1002/admi.202202471 0 e1037935-1c2b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209494 Fakulteta za strojništvo 0 0 0
