# TIL that there is already a Cellphone that Works Without Battery! ______________________________________________ <center> [Image Credit]( http://batteryfreephone.cs.washington.edu/)</center> I still can not believe that researchers at the University of Washington have created a cellphone that works without battery. And I will quote the article where I read about it. They express very well in a sentence one of the meanings of this new invention. > ... a major leap forward in moving beyond chargers, cords and dying phones. - UWToday The phone instead of using battery grasps the energy to be able to function of radio signals or the light. The research team even made Skype calls. <center> [Image Credit]( http://batteryfreephone.cs.washington.edu/)</center> One of the keys to achieving this was to think about how a telephone was designed and to review all processes that consume a lot of energy, such as the conversion of analog signals that transmit the sound in digital data that a phone can understand. According to them is one of the processes that consumes the most energy making the use of batteries mandatory. # This is a video about the cell phone without battery in use. _________________________________________ https://www.youtube.com/watch?v=5f5JJTmbO4U <center>[Video Credit]( https://www.youtube.com/channel/UCfSiYryINctnCaKe-jilVeA)</center> To know more details about the cellphone here I leave the [link where TIL this](https://www.washington.edu/news/2017/07/05/first-battery-free-cell-phone-makes-calls-by-harvesting-ambient-power/).
