Liquid Metal Machine Triggered Violin‐Like Wire Oscillator

Abstract

<b>The first ever oscillation phenomenon of a copper wire embraced inside a self-powered liquid metal machine</b> is discovered. When contacting a copper wire to liquid metal machine, it would be swallowed inside and then reciprocally moves back and forth, just like a violin bow. Such oscillation could be easily regulated by touching a steel needle on the liquid metal surface.
