title: Liquid Metal Machine Triggered Violin-Like Wire Oscillator.
abstract: The first ever oscillation phenomenon of a copper wire embraced inside a self-powered liquid metal machineis 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.
