TIL that there is already a Cellphone that Works Without Battery!

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.

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.
To know more details about the cellphone here I leave the link where TIL this.
And the direct link to the project website.
Did you know about the existence of this cellphone that does not use battery?
@juanmiguelsalas
I have also read an article where cell phones battery will be charged by the movements of the phone.
Yes, but this is possible since a long time as far as I know, you have old clocks who can do that :)
This is amazing. And you go to the website and everything on how it is built and how it works is there.
Yes, they even have a "White paper" PDF explaining everything! Amazing!
Thanks for the comment @buster544 :)
This was part of Nikola Tesla's original vision and goals. Free energy transmitted wirelessly. This is making use of those principles. Greed and the beginnings of big oil killed that dream for all of us. One day it will be realized.
I got all the writes from Nikola Tesla in a PDF not so long ago... still need some time to check them out. Thanks for the comment @steempowerpics
He was ahead of his time, but at least we have AC power thanks to him, if DC would have won the early battle electrical power would not be as to use.
Thank you for this highly interesting post. This proves that any small device is able to communicate with only environmental signals.
Yes, it looks like it is possible... greed make it impossible ;) Thanks for the comment @lucky.digger!
Haha great invention dude :P
