What if you could charge your phone on the fly, by sucking the juice from your friend’s smartphone? Well, that might sound like a zombie; but it’s something most of us really need. Sadly, such a technology is not yet available in the consumer market. With that said, Sony is apparently working on such a wireless charging technology and has, in fact, filed a patent for the same.

The patent application filed with US office reveal a method for wireless transfer of power and data between two consumer electronics, starting from smartphones to refrigerators. This is made possible using an antenna system. For starters, this antenna system will have at least two antennas – one for wireless data transfer and another for electricity transfer. The patent document further reveals that the system prototype developed by three Sony engineers James Richard, True Xiong and Charles McCoy uses an application to search for nearby wireless electricity transfer antenna just like WiFi hotspots.

The concept of transferring wireless electricity from one device to charge another device is quite similar to that of wireless hotspots, wherein a device function as a transmitter and the other acts as a receiver. That aside, the application that helps connect with a wireless electricity transmitting device will help you manually choose and select one in case there are multiple such devices near you.

It’s however, worth noting that this system prevents a smartphone from transmitting electricity wirelessly when it itself is running low on battery. Additionally, the transmitting device needs to plug into a charging socket in order to transmit electricity.

While this technology is still in its basic stages, it indeed appears to be quite promising. What’s more interesting is the fact that Sony has been working on this for the last three years. The Japanese OEM apparently filed its first patent for this antenna system back on May 29, 2014, and this latest application is merely a continuation of the same.
