GuRu’s modular wireless power transfer system can power a drone indefinitely

California-based company GuRu Wireless has recently developed and showcased a scalable and modular wireless power transfer system that is capable of delivering power to a high-power device up to several kilowatts, such as a drone, from up to 30 feet away (a little over 9 meters). They also mention that the system can power low-power devices, like LEDs and consumer electronics, over distances of several kilometers. It’s quite an extension to the GuRu’s desk-range wireless power evaluation kit we covered in 2020. The system uses 24 GHz high-frequency millimeter-wave radio signals to deliver energy over long distances without needing batteries or tethered systems. GuRu’s system uses a phased array transmitter with proprietary RFICs, to precisely deliver power to the receiver called the Recovery Unit (RU). In a recent demonstration video, GuRu Wireless showcased their wireless power transfer system by powering a drone from 30 feet away, operating it continuously for […]
