Faced with the existing situation, Huawei took the lead in making changes, and recently applied for a patent-it can charge smart terminals through lasers. From a conceptual point of view, laser charging is still very novel. More importantly, it is convenient. Laser charging does not require smart devices to be attached to chargers or wireless chargers. It can charge the intelligent terminal with preset power within a certain distance, which is a complete subversion of the traditional charging method.
But the problem also exists. We all know that laser is not widely used because it is harmful to human eyes. Exposure for a certain period of time will affect the vision of human eyes. The realization of laser charging inevitably represents that there are dangerous factors in our daily environment.
However, Huawei seems to have found a solution. According to @ Fast Technology 218, Huawei's laser charging has a safety function, that is, it automatically turns off the charging when the human eye is detected, thus preventing the laser from irradiating the human eye. However, new problems have emerged. If there are few people in the area, occasionally someone looks directly at the laser transmitter. When the number of people increases, the probability of looking directly at the laser transmitter increases greatly. So will the user's charging experience be affected? After all, the charging is automatically turned off when human eyes are detected.
whether it is innovative or convenient, laser charging is unique. But now it is only a patent. Huawei expects that it will be two or three years before it can see the commercialization of laser charging technology. It may be Huawei Mate 8 series or Glory 7 series, and the blessing of laser charging will promote the perfection of products.
