Huawei wants wireless charging to your mobile using laser. Huawei’s R & D & I laboratory continues to perform fully despite the difficulties that its mobile division is currently facing in the market. The last thing they are working on, or at least the last thing to be revealed, is true wireless charging. No contact charging, the inductive charging that we enjoy at the moment, but rather leaving the phone anywhere in the room and let it start charging “magically”.
We put quotation marks, of course, because here magic would not intervene but science. Specifically, the science of lasers. From Huawei they tell us that they are already exploring the possibility of remote charging through the use of lasers. Not only that, they also want the concept to be in circulation within two or three generations, that is, in a couple of years or three.
Photovoltaic cells for remote charging
As we usually say in these cases, patents do not necessarily end in real products but rather reflect the lines of research of different manufacturers. However, Huawei has been the one who has spoken of having the product in circulation in two or three generations of mobile phones , so it seems that they are quite serious with the project.
Authentic wireless charging has been talked about for a long time, and models such as ultrasonic are being considered, but until now a viable or safe method has not been designed. Huawei seems to want to follow the same principle that governs charging with solar energy but replacing visible radiation, sunlight, with mechanically generated light. Huawei wants to infuse power into mobile phones and other devices by laser.
The process is not explained although the video that accompanies the ad is quite self explanatory. Huawei is studying the possibility that a charger located on the ceiling (to maximize lines of sight) locates our mobile phones and can transmit power to them without contact and at a considerable distance. Also, the video shows how several terminals would be charged at the same time.
The principle of radiant radiation has been in use for a long time and has also been explored in telecommunications via Li-Fi , but now Huawei wants to use it to transmit energy. Thus, the charger would emit a series of laser light beams, invisible to our eyes because they are in the infrared light spectrum, which would locate the photovoltaic cells of the devices in order to establish a direct link and transmit energy. The search would be omnidirectional but the transmission of energy would be direct. Phones would use these cells to convert light into electricity and start charging.
Huawei wireless charging: An interesting concept with problems to solve
As in the case of the Li-Fi, the concept seems viable but it has an important starting point. A laser would require uninterrupted direct line of sight from the charger to the mobile phone, so charging could be intermittent if the phone is not placed in the proper position. On the other hand, it would be necessary to see how Huawei solves the fact that transmitting energy could damage objects, surfaces and also people themselves in the case of involuntarily intercepting these lasers. We imagine that it would be a very low intensity radiation but Huawei does not specify it. So we would talk about a remote but very slow charge. Of course, constant over time.
We will see what this line of research by Huawei about a new wireless charging system, really wireless, that could be used to power not only mobile phones but other devices with low energy consumption. All at once, with lasers emerging from the same charger. Or who knows, maybe starting from different chargers located at different points.
