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. %@ 0013-5194 %T Ferrofluidic actuation of liquid metal for radio-frequency applications %B Electronics Letters %D February 2018 %V 54 %N 3 %P 151-153 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=1097jcwugsjnh.x-iet-live-01content/journals/10.1049/el.2017.4108 %G EN
