Forget the charger: you can soon use an iPhone without a battery


Imagine it: in a day not too distant, your iPhone will not need to be charged . This fascinating fact could become a reality thanks to researchers from the University of Washington who have created a prototype mobile phone that does not require a battery to operate. Obviously, the functionalities of this terminal are far from those of a high-end smartphone, but there is less so that it can materialize.
This efficient prototype requires only 3.5 microwatts to operate and its way of achieving them is through the radio signals of the environment and of the light - it has a solar cell of the size of a grain of rice - to transmit signals To the base that is located about 20 meters away.
Its construction is made with very simple materials: capacitive buttons, a circuit with silicon base and other components of these that abound by any electronic laboratory. But most impressive of all is that the team of scientists has created a base to transmit the signal with so little energy requirement .
With this facility, researchers have successfully managed to make and receive calls via Skype and leave calls on hold. Of course, this is only the beginning: the next step will be to integrate an electronic ink display that allows video streaming and encryption of calls to increase security.
Obviously, thinking about an iPhone or a Samsung working in the short term is a chimera , but with the reality is that there is a double trend that could make it possible: this fascinating invention and that more and more manufacturers strive to make their equipment More energy efficient. And so ambitious is his goal, says one of the authors of the paper called Vamsi Tall:
SOON YOU WILL BE ABLE TO IMAGINE THE FUTURE WITH WI-FI ROUTERS THAT WORK IN THIS WAY, BECAUSE BY PLACING ONE OF THESE IN YOUR HOUSE, YOU CAN HAVE COVERAGE AND CHARGE OF TELEPHONE IN THE NEXT AREA.
