The trick: it converts some of the radio signals emanating from a phone into direct current (DC) power, which then charges the phone\u2019s battery, they state.<\/p>\n<p>This new technology can be built into a cell phone case, adding minimal bulk and weight.<\/p>\n<p>\u201cWhen we communicate with a cell tower or Wi-Fi router, so much energy goes to waste,\u201d explained\u00a0<a href=\"https:\/\/ece.osu.edu\/people\/chen\">Chi-Chih Chen<\/a>, research associate professor of\u00a0<a href=\"https:\/\/ece.osu.edu\/\">electrical and computer engineering<\/a>. \u201cWe recycle some of that wasted energy back into the battery.\u201d<\/p>\n<p>\u201cOur technology is based on harvesting energy directly from the source, explained <a href=\"https:\/\/ece.osu.edu\/people\/rlee\">Robert Lee<\/a>, professor of electrical and computer engineering. By Lee\u2019s reckoning, nearly 97 percent of cell phone signals never reach a destination and are simply lost. Some of the that energy can be captured.<\/p>\n<p>The idea is to siphon off just enough of the radio signal to noticeably slow battery drain, but not enough to degrade voice quality or data transmission. Cell phones broadcast in all directions at once to reach the nearest cell tower or Wi-Fi router. Chen and his colleagues came up with a system that identifies which radio signals are being wasted. It works only when a phone is transmitting.<\/p>\n<p>Next, the engineers want to insert the device into a \u201cskin\u201d that sticks directly to a phone, or better, partner with a manufacturer to build it directly into a phone, tablet or other portable electronic device.<\/p>\n<p><em>UPDATE June 6: Responding to a request for more information on energy harvesting, we received the following statement from Will Zell, CEO of licensee Nikola Labs: &#8220;Nikola Labs has a limit to the technical details we are able to share until our patents are published.&#8221;<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Engineers&nbsp; at The Ohio State University claim they have created a circuit that makes cell phone batteries last up to 30 percent longer on a single charge.
