Metal aesthetics of metallic jewelry. Some metals have specialized uses; mercury is a liquid at room temperature and is used in switches to complete a circuit when it flows over the switch contacts. Radioactive metals such as uranium and plutonium are used in nuclear power plants to produce energy via nuclear fission. Shape memory alloys are used for applications such as pipes, fasteners and vascular stents. Metals can be doped with foreign molecules—organic, inorganic, biological and polymers. This doping entails the metal with new properties that are induced by the guest molecules. Applications in catalysis, medicine, electrochemical cells, corrosion and more
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
