Wireless TV
As new TVs become thinner and lighter, their creators are looking for opportunities to install their brainchild almost anywhere, including without using it... the usual power cord.
Russian startup Reasonance presented a prototype of a wireless TV at CES 2021. It uses a technology that is able to transmit energy over a distance of up to a meter. Moreover, the company guarantees the possibility of increasing the range, thanks to the adjustment of the size of the conductive coils. Wireless power transmission is provided by an external receiving coil on the back of the TV. The developers claim that it could be integrated directly into the TV frame, but this would somewhat "inflate"a flat 40-inch TV.

The problem was solved by installing the coil in a special table located under the base of the TV. The system provides transmission of 120 watts of power with a frequency of 20 to 120 kHz over a distance of up to half a meter. An attempt to create its own wireless TV has already been made by Samsung, but the presentation of its prototype at last year's CES did not take place: the developers decided that it was still too "raw". Reasonance believes that they have solved the problem of the ratio of efficiency and cost of the system, which allows it to be integrated into market products. The company has patented its know-how in Russia and sent patent applications to the US, EU, China, India, Canada and South Korea.
