Scientists at the Naval Information Warfare Center–Pacific have recently invented a system that allows for wireless power and data transfer between unmanned vehicles. The patented technology is available via patent license agreement to companies that would make, use, or sell it commercially.

Unmanned vehicles have attracted attention in recent years for applications such as service delivery, pollution mitigation, farming, and rescue operations. However, the battery drains quickly in many cases and requires frequent recharging, which poses an inconvenience. The military and various other industries require a reliable, effective way to transfer power wirelessly to unmanned vehicles, sensor units, and refueling units.

The charging system could be used to charge autonomous vehicles such as the one shown. Flickr

To this end, Navy researchers developed the wireless power transfer system that can be used to charge unmanned vehicles.

The invention consists of a transmitting coil and a receiving coil which, when placed in close proximity to one another, automatically exchange power and data signals. Although the system is configured to work in an underwater environment, it can also operate in a land-based or air-based environment.
