Ionic imbalance induced self-propulsion of liquid metals
The control over the motion and deformation of liquid droplets is essential to many microfluidic and actuation systems. Zavabeti et al. demonstrate that applying a pH or ionic gradient across a droplet of liquid metal alloy of gallium results in its motion due to a breaking of the surface charge sym...
