Making antennas from liquid metals should mean robust reception
From radios and mobiles phones to wireless-networking gear and satellite-navigation devices, antennas are everywhere. Yet they are delicate pieces of equipment. Civilians, for the most part, take them for granted, but the armed forces know just how easily an antenna can be destroyed in a war zone—with potentially catastrophic consequences. Now, a technology that allows antennas to bend fluidly and “self heal” as they get whacked around in the chaos of war could make using them a great deal easier.
Dr Dickey put together a team of electrical and chemical engineers and, together, they started looking at metals and metal alloys that are soft at room temperature. The best mix they came up with was an alloy of gallium and indium. This had all the electrical properties that antennas need to function, but was much more flexible than its copper equivalent. Indeed, it was more than just flexible. At room temperature it was actually liquid, and thus flowed when deformed, rather than breaking.
The result is an antenna that can be housed in a variety of covers, appropriate to different uses. Rigid casings will make the antenna more solid and rubber ones will allow it to stretch like an elastic band.
