The most common use of the wireless charging phenomenon of electromagnetic induction and work within a limited range: to achieve acceptable efficiency of electricity transmission over the air . Significantly increase the transmission distance will allow the technology using ultrasonic waves, invented by uBeam.
Now uBeam able to make fully functional prototype on which subsequently can be created commercial devices. The transmitter shown uBeam, is a tablet thickness of about 5 mm, which creates sound waves . Receiver is designed as a different, more of a thin plate that can be placed, for example, on the back of the smartphone.
First Ultrasound technology transfer was shown in 2011. Then it was on the range of the transmission of 7-10 meters, power charger not specified.
uBeam believe that the technology of ultrasound transmission finds application not only in battery chargers for smartphones, but also, for example, in the ecosystem of smart home. Related Products :
