Tunable Liquid Metal Antennas | American Institute of Physics : Tunable Liquid Metal Antennas.  Using electrochemistry, North Carolina State University researchers have created a reconfigurable, voltage-controlled liquid metal antenna that may play a huge role in future mobile devices and the coming Internet of Things From the Journal:Journal of Applied Physics By AIP News Staff. WASHINGTON D.C., May 19, 2015 -- Researchers have held tremendous interest in liquid metal electronics for many years, but a significant and unfortunate drawback slowing the advance of such devices is that they tend to require external pumps that can't be easily integrated into electronic systems. So a team of North Carolina State University (NCSU) researchers set out to create a reconfigurable liquid metal antenna controlled by voltage only, which they describe in the Journal of Applied Physics, from AIP Publishing. The team's work was inspired by a phenomenon recently observed during studies ...
