The developers used graphene material incombined with silicon to create wearable solid sensors. This approach has solved the corrosion, durability and skin contact resistance issues that have hampered everyday use of existing technologies, the engineers say.
Hexagonal graphene pattern sensorslocated on the back of the head to detect waves from the visual cortex of the brain. The contacts are resistant to harsh conditions, so they can be used in extreme conditions.

Devices are managed usinga special augmented reality lens installed in front of the user's gaze. White flickering squares appear on the screen. When the operator concentrates on a certain square, his brain waves are captured by a biosensor, and the decoder translates the signal into commands.
Our technology can produce at least ninecommands in two seconds. This means that we have nine different types of commands and the operator can choose one of these nine during this period of time.

Researchers have demonstrateddevices for controlling the four-legged robot Ghost Robotics. The experiment showed that a trained operator can control the robot with up to 94% accuracy without the help of hands. Engineers believe that the development will find applications in manufacturing, aerospace and healthcare.
