In article number 1905067, Wei Wang, Xing Ma, and co‐workers report the fabrication of a liquid metal micro/nanomotor (LM‐MNM) made of Galinstan (a gallium–indium–tin alloy). These small LM‐MNMs (with a size of a few hundred nanometers) are half‐coated with a thin layer of platinum (Pt) and move in H 2 O 2 via self‐electrophoresis. Their potential as an on‐demand, self‐targeting welding filler is demonstrated through their movement and accumulation at junctions in a silver nanowire network.
