Wireless charging in mobile phones isn’t something new. In 2012, Nokia Lumia phones shipped with Qi wireless charging and manufacturers such as Samsung, Google, and LG have incorporated the concept since, with Apple planning to introduce the feature in iPhone 8.

In a new patent filed in the US, Sony has shown how it plans to take this technology a step further.

The patent describes an antenna system that would allow a device, such as a mobile phone, to transfer power from a wireless charging base station. It also suggests antennas could transmit power from one consumer electronic (CE) device to another. For example, one phone could provide power to another.

“At least the first antenna system is cooperated with a first CE device and the second antenna system is cooperated with a separate second CE device,” the patent says.

“The system provides a graphical user interface to illustrate each of the identified antenna systems, and receives user instructions corresponding to at least two of the identified antenna systems, to generate configuration instructions in accordance with the user instructions, and to configure selected CE devices in accordance with the configuration instructions”.

But it should be kept in mind that the creation of the document and filing of the idea doesn’t mean that it is definitely coming to reality anytime soon. Most patents are created to protect future ideas or for technologies that aren’t capable at present and will only ever remain on paper.

However, Disney researchers have been working on developing the theories for wireless power that can be used across a room.

“An experimental demonstration shows that a 54 m3 QSCR room can deliver power to small coil receivers in nearly any position with 40% to 95% efficiency,” Disney researchers wrote in February 2017.

“Finally, a detailed safety analysis shows that up to 1900 watts can be transmitted to a coil receiver enabling safe and ubiquitous wireless power.”
