A global system of wireless transmission of electricity or wireless power has been propped by the team of researchers many years ago but one main key difficulty in order to realize this ambitious vision was the inefficiency of transferring power over long distances.
A number of definitive steps were taken by the team of researchers towards more practical wireless charging but now this wireless electricity technology has been licensed through the researchers which will be able to apply in mobile devices, electrical vehicles along with a host of other applications potentially.
The ultimate goal of this technology is to forge toward a wire free world through which there will be no need for consumers to carry wires and power ricks. This technology will also provide benefits to smaller batteries as well as less hardware which would lead lower cost for manufacturers and consumers.
Wireless technology has the potential to change the world for a better place. The present technology has the ability to charge device at around 6 to 12 inches with 95 percent efficiency roughly as well as 12 watts in case of mobile devices and up to 6.7 kilowatts for cars.
With the advancement in the technology and through research and development, distance, scale and efficiency are being increased by the researchers. There is also the development of repeaters which are kinds of passive devices through which the distance of the power can be extended.
A similar kind of wireless charging technologies have been around for some time such as: traditional induction charging through which electromagnetic field is used in order to transfer energy between two coils, has been used in transformers. In past few years, there is an increment in wireless cell phones which is based on inductions.
In order to move energy between two points for example: two satellites, lasers can also be used but it requires an uninterrupted, continuous path between the transmitter and the receiver which is not ideal for consumer products.
In order to make the system more efficient, researchers tunes the coils for finding a strong electromagnetic highly resonant coupling. It has been founded by the researchers that it is similar to a tuning fork vibrating when exposed to a sound of the right frequency or a radio antenna tuning into a single station out of hundreds.
