Researchers find the macroscopic Brownian motion phenomena of self-powered liquid metal motors

(Science China Press) The classical Brownian motion, resulted from microscopic molecule collisions, has been found for more than one hundred years. Recently, researchers disclosed the macroscopic Brownian motion phenomenon of the interiorly driven liquid metal tiny motors in alkaline solution. The driving force comes from propulsions of the hydrogen bubbles generated from bottom of the millimeter scale tiny motors contacting the substrate. The established optical image contrast platform distingu...
