20.500.12556/RUL-143412 Nematic colloidal micro-robots as physically intelligent systems Physically intelligent micro-robotic systems exploit information embedded in micro-robots, their colloidal cargo, and their milieu to interact, assemble, and form functional structures. Nonlinear anisotropic fluids such as nematic liquid crystals (NLCs) provide untapped opportunities to embed interactions via their topological defects, complex elastic responses, and ability to dramatically restructure in dynamic settings. Here a four-armed ferromagnetic micro-robot is designed and fabricated to embed and dynamically reconfigure information in the nematic director field, generating a suite of physical interactions for cargo manipulation. The micro-robot shape and surface chemistry are designed to generate a nemato-elastic energy landscape in the domain that defines multiple modes of emergent, bottom-up interactions with passive colloids. Micro-robot rotation expands the ability to sculpt interactions; the energy landscape around a rotating micro-robot is dynamically reconfigured by complex far-from-equilibrium dynamics of the micro-robot’s companion topological defect. These defect dynamics allow transient information to be programmed into the domain and exploited. Robust micro-robotic manipulation strategies are demonstrated that exploit these diverse modes of nemato-elastic interaction to achieve cargo docking, transport, release, and assembly of complex reconfigurable structures at multi-stable sites. Such structures are of great interest to future developments of LC-based advanced optical device and micro-manufacturing in anisotropic environments. active soft materials nematic colloids micro-robots nonlinear dynamics topology directed assembly emergent interactions aktivna mehka snov nematski koloidi mikroroboti nelinearna dinamika topologija true false true Angleški jezik Slovenski jezik Članek v reviji 2022-12-20 10:26:37 2022-12-20 10:26:38 2022-12-21 03:36:49 0000-00-00 00:00:00 2022 0 0 13 str. iss. 44, art. 2205546 Vol. 32 Oct. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 1616-301X 10.1002/adfm.202205546 119422979 Adv_Funct_Materials_-_2022_-_Yao_-_Nematic_Colloidal_Micro‐Robots_as_Physic.pdf Adv_Funct_Materials_-_2022_-_Yao_-_Nematic_Colloidal_Micro‐Robots_as_Physic.pdf 1 C5B9F08103822AAF6AC12C289B5AD030 43f1b02238420de1405ee810ce3669dff9b8cdac962250ec6335c08c2662c8f2 7fe84546-804e-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165087 https://onlinelibrary.wiley.com/doi/10.1002/adfm.202205546 0 7a9ca5c1-8048-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165076 Fakulteta za matematiko in fiziko 0 0 0
