No battery phone!! Will it be our future??

I know many people out here are tensed with their battery problems. Clearly, this is a serious issue as we use our smartphones for about 2 hrs daily and then charge upto 3hrs. So, clealry, there is a lot of energy imbalance but what if there are no battery smartphones from now on?? Scientists are researching and finding the way out off battery in smartphones:

 

 

How is the phone made? What are the technologies used?

  • The phone pulls power from its environment - either from ambient radio signals harvested by an antenna, or ambient light collected by a solar cell the size of a grain of rice.
  • The device consumes just 3.5 microwatts of power during use.
  • The biggest step was eliminating the analog-to-digital converter that turns your voice into data. Instead, they took advantage of tiny vibrations that happen in a microphone when a person is talking into it, or a speaker when someone is listening.

 

Use of Antenna and Buttons:

An antenna converts that motion into radio signals in a way that uses almost no power. The only downside is that the user has to press a button to switch between speaking and listening modes. In testing, the team was able to make calls and even use Skype.

Right now the battery-free phone needs a custom base station to transmit and receive calls. But the team says there's no reason why the technology couldn't be integrated into standard mobile network infrastructure.

“You could imagine in the future that all cell towers or Wi-Fi routers could come with our base station technology embedded in it,” said co-author Vamsi Talla, a former UW electrical engineering doctoral student and Allen School research associate.

“And if every house has a Wi-Fi router in it, you could get battery-free cellphone coverage everywhere."
