Liquid metal amoeba with spontaneous pseudopodia formation and motion capability

Abstract The unique motion of amoeba with a deformable body has long been an intriguing issue in scientific fields ranging from physics, bionics to mechanics. So far, most of the currently available artificial machines are still hard to achieve the complicated amoeba-like behaviors including stretch...
