We are living in an era where technology is improving day by day and providing us with new things every day. To surprise us even more Researchers at Disney Research are working on a method to provide electricity to charge mobile phones and other devices without a cord. 

The researchers are working on the method to charge mobile phones simultaneously, and power other devices without connecting the electronic devices to a charger. The process of receiving the electric energy will be done on the basis of the principles of WiFi, the metalised walls and floors are induced with electric current and magnetic field is generated through which the coils get power and hence the device is charged or powered.  Hence no cord is required. The induced currents in the structure are channelled through discrete capacitors, which isolate potentially harmful electrical fields.

This new method was published in the journal PLOS ONE, for wirelessly transmitting power throughout a room which enables users to charge electronic devices as they use WiFi. They called their method quasistatic cavity  resonance (QSCR), inside a specially built 16-by-16-foot room at their lab.

Alanson Sample, Associate Lab Director and principle research Scientist, Disney Research, said that, “This new innovative method will make it possible for electrical power to become as ubiquitous as WiFi.This in turn could enable new applications for robots and other small mobile devices by eliminating the need to replace batteries and wires for charging. In this work, we’ve demonstrated room-scale wireless power, but there’s no reason we couldn’t scale this down to the size of a toy chest or up to the size of a warehouse.”  He also said that wireless power transmission technology is a long term technological dream.

“Our simulations show we can transmit 1.9 kilowatts of power while meeting federal safety guidelines,” Chabalko said, adding that this was equivalent to simultaneously charging 320 smartphones.
