Since years, our mobile phones are no longer sporting those ugly <strong>extendable<\/strong> antennas, that needed to be spread out each time you answered the phone, and that had a hard (and often short) life. Nowadays, <strong>antennas<\/strong> are concealed within the <strong>casing<\/strong> of our phones, and soon we might see, in this field as well as in others, <strong>liquid metal<\/strong> flexible antennas.<\/p>\n<p style=\"text-align: justify;\">Those <strong>flexible antennas<\/strong>, manufactured with an <strong>alloy<\/strong> of indium and gallium which stays in a liquid state, are the subject of a <strong>North Carolina <\/strong>State University research.<br \/>\nThe alloy is injected inside extremely thin <strong>channels<\/strong>, the size of a hair. Once it is in, it forms some sort of <strong>skin<\/strong> which holds the alloy in place and allows it to remain <strong>liquid<\/strong>.<\/p>\n<h3>How these <a href=\"https:\/\/iopscience.iop.org\/article\/10.1088\/1742-6596\/1878\/1\/012068\" target=\"_blank\" rel=\"noopener\">flexible antennas<\/a> work?<\/h3>\n<p style=\"text-align: justify;\">Thanks to this, antennas are extremely <strong>flexible<\/strong>, and since an antenna\u2019s frequency is influenced by its <strong>shape<\/strong>, shortening or lengthening them means changing their receiving <strong>properties<\/strong> according to one\u2019s need. Along with this feature, which makes it useful for devices already on the market, its high <strong>durability<\/strong> makes it ideal for applications where <strong>sturdiness<\/strong> is a must, for example in the <strong>military<\/strong> field or to monitor the condition of civilian <strong>installations<\/strong> such as skyscrapers or bridges.<\/p>\n<p style=\"text-align: justify;\">For example, as we know, <strong>bridges<\/strong> stretch and expand with wind, <strong>temperature<\/strong> changes or the weight of passing cars. By inserting such an antenna in the right <strong>position<\/strong>, it would change its shape according to these factors, and would provide useful <strong>information<\/strong> on the bridge\u2019s health.<\/p>\n<p style=\"text-align: justify;\">Currently, the high cost of the <strong>gallium-indium<\/strong> alloy makes it possible to foresee its use for this kind of installations, but in a near future we might be able to see them inside our <strong>mobile phones<\/strong> or <a href=\"https:\/\/www.endoacustica.com\/\">GPS positioning systems<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Flexible Antennas?
