Most mini flyer drones for consumers can fly for 10 minutes to 30 minutes, and to extend the cruising range, equipping the battery with a larger capacity seems the only one way. However, doing so will actually increase the load of the drone, and the effect on extending the flight time is not obvious. In order to solve this problem, a researcher has developed a new type of drone technology that can make the drone keep flying without a battery.
Dr. Samer Aldhaher from Imperial College London has developed the latest ultralight mini flyer drone
, and its power comes entirely from a wireless transmitter. However, there are still many restrictions on the use of this technology. For example, the drone cannot exceed 5 inches in size and can only perform simple lateral movement, but it seems a good beginning for future development.
It should also be noted that Aldhaher's prototype is based entirely on custom hardware developed by himself, so it will damage many transistors due to the use of high-frequency power, so if you use too cheap components, it will also affect the flight time.
There are still many difficulties in the promotion of this technology, and it takes a long process. Moreover, large-scale coverage also requires a certain degree of infrastructure construction. But if such a wireless power solution can really be used, then the arrival of this day may not be far away.
