The company uBeam introduced the technology of wireless charging devices based on ultrasound

The other day the web has information about a very interesting development: wireless charging of gadgets using ultrasound. The development is presented by uBeam, and is the conversion of electric charge into ultrasound, which catches the receiver attached to any device. Then the inverse transform occurs, and the device battery charges.

So far only an early prototype of this type of charge is ready, so it is difficult to judge the efficiency of such a transmission. Nevertheless, the advantages of the new technology is the ability to charge devices at a greater distance than in the case of using existing wireless charging. Of course, the ultrasound will not pass through the wall, but within the room the charging will go without problems.

So you can imagine cafes, offices and apartments equipped with such charges. When a person with an ultrasound-adapted gadget enters the room, the battery immediately starts charging, no wires of any kind are needed on which the devices are put for the traditional method of wireless charging.

According to the head of the company, which has developed a new technology, the charging stations of the new type will be small, their thickness will not exceed 5 mm. Such transmitters can be placed on the walls, ceiling, making them invisible to humans.

In this new technology can be used to charge not only the battery of a mobile device, tablet or smartphone, but also a laptop. The receiver also promises to be miniature, so in the case of the same tablet or laptop there will be no problem. Probably, for the smartphone developers will find a suitable option.

In the opinion of the developers, such technology will enter the market in about two years. At the same time there will be several options for ultrasonic charging devices: for small rooms, such as offices and rooms, and for supermarkets, airports and other facilities, where there is usually a huge number of visitors with a large number of devices.
