ResumoA new method is presented for actuating liquid metals, based on the physical deformation of ferrofluid in response to an applied magnetic field. Using this ferrofluidic actuation, a liquid-metal slug was moved through a channel at an average velocity of 15.6 mm/s. The hydrocarbon-based ferrofluid exhibits negligible loss from 50 MHz to 20 GHz, and can thus serve as an alternative carrier fluid to hydrochloric acid or sodium hydroxide for liquid-metal-based reconfigurable radio-frequency circuits.
