Liquid metal will wet to most metallic surfaces. Specifically though, room-temperature liquid metal can be very reactive with certain metals. Liquid metal can dissolve most metals; however, at moderate temperatures, only some are slightly soluble, such as sodium, potassium, gold, magnesium, lead, nickel and mercury. Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion, more so than niobium, titanium and molybdenum. Similar to indium, gallium and gallium-containing alloys have the ability to wet to many non-metallic surfaces such as glass and quartz. Gently rubbing the alloy into the surface may help induce wetting. However,
Liquid metal make a small flexible antenna. In Mathieu's paper, a method for implementing a 3D flexible antenna is proposed. The method uses a Fused Deposition Modeling (FDM) technique to fabricate a dielectric radome in a NinjaFlex flexible plastic. This technique can also be used to design fully flexible antennas. The main advantage of this method is that it can realize 3D structures with large thickness values. Antenna material and structural parameters like this: 1. the Galinstan liquid metal(68.5%Ga, 21.5%In, 10%Sn, conductivity3.46×106S/m), which is used to realize the radiating element; 2. the NinjaFlex flexible plastic used to realize, through a 3D FDM
