Classical Brownian motion theory was established over one hundred year ago, describing the stochastic collision behaviors between surrounding molecules. Recently, researchers from the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences discovered that self-powered liquid metal motors at the millimeter scale demonstrated similar Brownian-like motion behaviors in alkaline solution. And the force comes from the hydrogen gas stream generated at the interface between the liquid metal motor and its contacting substrate bottom.
