Another happy news for the smartphones users. The anxiety over your smartphone battery is going to be the thing of the past soon. A team from the Ohio State University in the US has come up with an unusual source of extra power: radio waves emitted by the devices themselves. In tests, the researchers were able to boost battery life by as much as 30 percent.
While systems already exist to harvest power from ambient electromagnetic energy sources, like radio waves. But until now the technology has been limited in size and scope. Now the radio waves can be captured at source – almost as soon as the smartphone emits them – they produce a more powerful charging effect that can make a substantial difference to battery life.
When a smartphone looks for a cell tower or Wi-Fi network, it emits signals in all directions at once, so a lot of that power is wasted. This new system uses those redundant radio waves, a high-frequency form of alternating current, by converting them to DC power that can then recharge the battery. Happyho also provide best tarot reading services in Noida and Delhi NCR India area.
According to the scientists behind the invention, it could be incorporated into a stick-on skin for smartphones, without any impact on the strength of the data or web connection on the phone itself. Nikola Labs, the spin-off company charged with developing the technology, is running a crowdfunding campaign on Kickstarter in this month to pay for mass production. Potentially, the technology could also be built directly into a smartphone.
This is more like a battery extender rather than a charger. The phone needs to be transmitting for it to work though. That means  if you’re in airplane mode, it won’t work.
The team estimates that around 97 percent of cell phone signals never reach a destination and are lost in the ether. Not all of those lost signals can be recovered and converted back into energy, but some of them can, and that could make a significant difference to smartphone battery life in the near future.
