Impacting Fuelling Dynamics Towards Tunable Liquid Metal Machine
Exploration, EarlyView.Confining liquid metal machines (LMMs) within one‐dimensional semi‐open channels reveals sustained, tuneable reciprocating dynamics, driven by fuel region evolution and boundary interactions. This work elucidates how spatial confinement and obstacle materials regulate symmetry‐breaking and directional control, enabling predictable LMM operation and ...
