US military scientists have used electrical brain stimulators to enhance mental skills of staff, in research that aims to boost the performance of air crews, drone operators and others in the armed forces’ most demanding roles.

The successful tests of the devices pave the way for servicemen and women to be wired up at critical times of duty, so that electrical pulses can be beamed into their brains to improve their effectiveness in high pressure situations.

The brain stimulation kits use five electrodes to send weak electric currents through the skull and into specific parts of the cortex. Previous studies have found evidence that by helping neurons to fire, these minor brain zaps can boost cognitive ability.

Given that the battery life of most multicopter drones typically doesn’t exceed 30 minutes of flight time per charge, there are many tasks that they simply can’t perform. Feeding them power through a hard-wired tether is one option, although that only works for applications where they’re hovering in place. Scientists at Imperial College London, however, are developing an alternative – they’re wirelessly transferring power to a drone as it’s flying.

For their study, the scientists started with an off-the-shelf mini quadcopter. They proceeded to remove its battery, add a copper coil to its body, and alter its electronics.

The researchers also built a separate transmitting platform that uses a circuit board, power source and copper coil of its own to produce a magnetic field. When placed near that platform, the drone’s coil acts as a receiving antenna for that magnetic field, inducing an alternating electrical current. The quadcopter’s rejigged electronics then convert that alternating current to direct current, which is used to power its flight.

Verizon has joined the likes of Facebook, Google and fellow telecommunications giant AT&T in exploring the potential of internet-connected unmanned aircraft. While its vision involves expanding 4G coverage across the US, it has an immediate focus on shoring up communications for first responders in emergency situations, and recently carried out trials to that effect.

Verizon has dubbed the initiative Airborne LTE Operations (ALO) and says it has actually been in the pipeline for around two years. The company has been working to integrate internet connectivity into unmanned aerial vehicles and hook them up to its 4G network, daisy chaining coverage and beaming it down to unconnected areas in the process. This is similar to how Facebook hopes its Aquila drones will work.

Verizon recently teamed up with company American Aerospace Technologies to see how using drones as gliding cell towers could have an impact in disaster relief scenarios. In a simulated mission in New Jersey, the team set a drone with a 17-foot (5.2 m) wingspan in flight to put the onboard technologies through their paces.
