There are more and more wireless technologies emerging. Bluetooth and WiFi have revolutionized the way we communicate on our devices. We can now wirelessly charge, although we still need a contact surface to create an electromagnetic field. Now, a new technology has been able to create a system for wirelessly transmitting electricity to power a television without cables.
CES expo is often the ideal place to showcase the most innovative technologies. In previous editions, we saw many demonstrations of devices operating wirelessly without cables. WattUp was one of the most promising projects, which stormed CES in 2017 with its wireless charging system. Later, they introduced Wireless Charging 2.0, which they equipped in different chips, and currently they are all in testing stages for medical equipment and low-power devices.
However, we have not seen consumer devices in a demonstration like what Reasonance did. This company showcased in a video how their wireless electricity technology works with a television at a distance of more than 50 cm, and at a 90-degree angle.
As we see in the video, there is no cable between them. To transmit electricity remotely without wires, it is necessary to create an electromagnetic field with a copper coil to emit and receive electricity. The principle is similar to the portable wireless charging principle Qi, where the phone and the charger have internal copper coils.
Thus, in this magnetic resonance imaging system, the coil can be integrated into the wall, while the coil of the receiving device can be integrated into the television itself. Thanks to this, you can have a truly cable-free television, or use it as if it were a Qi charger but for TVs.
