Sony has recently published a patent application for wireless energy transfer.

The abstract of the “Wireless Power and Communication System” is as follows;

The present invention provides a wireless communication apparatus including: a communication processing unit that transmits and receives a radio signal; a wireless power transmitting unit that supplies power wirelessly to an apparatus located within a power supplyable range; a location data obtaining unit that obtains location data of a power receiver apparatus; and a control unit that controls a power supply to the power receiver apparatus based on the location data of the power receiver apparatus obtained by the location data obtaining unit.

In some of the cases, this technology can enable one device to pass the energy to another, if the main power hub is tied up. This technology is interesting as it would enable us in the very near future that we can charge our mobile devices without worrying us for a wire or charging plate.

In another report, Qualcomm, mobile chip manufacturer, and Samsung have joined hands in the establishment of the Alliance for Wireless Power (A4WP), announced in May during CTIA Wireless 2012. Infact, Samsung’s latest smartphone, Galaxy SIII has been equipped with wireless charging facility.
