ease congestion over the airways by improving the performance of new and old cell phones as well other forms of portable devices.&nbsp; Scientists have discovered how they can mass-produce small mechanical devices that can assist the users of cell phones in avoiding the nuisances of slow downloads and dropped calls.<\/p>\n<p class=\"mb10\">\u201cThere is not enough radio spectrum to account for everybody\u2019s handheld portable device,\u201d says Purdue University associate professor of mechanical engineering, Jeffrey Rhoads.&nbsp; Because of overcrowding, users of cell phones experience the frustration of busy signals, slower download and degraded call quality.&nbsp; In order to counter the problem, the industry is attempting to build systems that will be able to operate with much more sharply defined channels so that a lot more of them will be able to fit into the bandwidth that is available.<!--more--><\/p>\n<p class=\"mb10\">\u201cTo do that you need more precise filters for cell phones and other radio devices, systems that reject noise and allow signals only near a given frequency to pass,\u201d says electrical and computer engineering associate professor Saeed Mohammadi, who is working alongside Rhoads as well as other researchers including doctoral student Hossein Pajouhi.<\/p>\n<p class=\"mb10\">The team has created devices known as nanoelectromechanical resonators that contain a small silicon beam that vibrates when voltage is applied.&nbsp; The researchers have demonstrators that these devices are created with a yield of almost 100 percent, which means that almost all of the devices created with silicon wafers functioned properly.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A tiny mechanical device known as an
