Wireless ultrasound smart phones charging
Ultrasounds cause vibrations which will create electricity.
The company produced a wireless charger which emits ultrasounds which will generate vibrations in a phone and they will then produce electricity, the French site, metronews.fr., reports.
The system should enable users to, in case their battery in a smart phone is
empty, continue communication via phone while a device is being charged and ot to be tied up to a charger of a cable.
A charger is still in a prototype stage but uBeam forecasts its
commercialization in four years.
Basically, the system could extend to all electricity devices.
