Chinese scientists recently achieved a research result that can make dynamic wireless charging more efficient. Its future application is expected to allow drones to charge while flying. Relevant results were recently published in the international academic journal Nature Communications.

The research group of Professor Li Long from the School of Electronic Engineering of Xi'an University of Electronic Science and Technology has made breakthrough progress in the fields of wireless energy transmission and wireless positioning. It has constructed a prototype system integrating wireless energy transmission, sensing positioning and communication based on dual-frequency metasurfaces, achieving Wireless energy transfer for adaptive tracking. In this system, the metasurface not only achieves precise target positioning, but also flexibly focuses energy according to the real-time changing environment and targets, achieving tracking and air-to-air energy transmission.

Compared with traditional wireless charging methods, this technology has significant advantages: it can support efficient non-contact wireless charging of multiple terminal devices during movement, such as moving drones, smart robots, etc., for which Provide stable and efficient power supply.

It is reported that the results of this paper were published with Xi'an University of Electronic Science and Technology as the first unit. Xia Dexiao, a doctoral student in the School of Electronic Engineering, is the first author of the paper. Professor Li Long and Academician Cui Tiejun of Southeast University are the co-corresponding authors.
