A new method of actuating liquid metal using capillary action via paper media is presented. This actuation method uses no electrical power and is capable of moving a liquid-metal slug up to 3 mm/s. A microstrip transmission line switch was fabricated to demonstrate this new actuation method. This switch has >40 dB isolation and <2 dB insertion loss across a 5-GHz span.
