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. Conceptually, laser charging is still very novel. More importantly, it is convenient. Laser charging does not require smart devices to connect 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 there are also problems. 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 human vision. The realization of laser charging inevitably represents the existence of dangerous factors in our daily environment.
However, Huawei seems to have found a solution. According to the introduction of @ Fast Technology 20 18, Huawei's laser charging has a safety function, which is to automatically turn off the charging when human eyes are detected, so as to prevent the laser from irradiating the human eyes. However, new problems have emerged. If there are few people in the area, occasionally someone will look 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 will be automatically turned off when human eyes are detected.
Whether innovative or convenient, laser charging is unique. But now it's just a patent. Huawei expects that it will take two or three years to see the commercialization of laser charging technology. It may be Huawei Mate 80 series or Glory 70 series. The blessing of laser charging will promote the improvement of products.
