Photochemically induced motion of liquid metal marbles
Photochemically induced motion of liquid metal marbles
We demonstrate photochemically induced actuation of liquid metal marbles, which are liquid metal droplets encased in micro/nanoparticles. The WO 3 nanoparticles coated marbles are placed in H2O 2 solution, and their surfaces are illuminated with UV light. The semiconducting WO3 coating behaves as a photocatalyst to trigger a photochemical reaction, generating oxygen bubbles that propel the marble. The actuation of the marbles is investigated under different H2O 2 concentrations, light intensities, and marble dimensions. Equations describing the fundamentals of such actuations are presented.

Abstract
We demonstrate photochemically induced actuation of liquid metal marbles, which are liquid metal droplets encased in micro/nanoparticles. The WO 3 nanoparticles coated marbles are placed in H2O 2 solution, and their surfaces are illuminated with UV light. The semiconducting WO3 coating behaves as a photocatalyst to trigger a photochemical reaction, generating oxygen bubbles that propel the marble. The actuation of the marbles is investigated under different H2O 2 concentrations, light intensities, and marble dimensions. Equations describing the fundamentals of such actuations are presented.
