Researchers develop graphene-biosensors for brain machine interfaces

Researchers at the University of Technology Sydney (UTS) have developed a novel graphene-based biosensor, set to drive new innovations in brain-controlled robotics.

The biosensor adheres to the skin of the face and head in order to detect electrical signals being sent by the brain. These signals can be translated into commands to control autonomous robotic systems. The sensor, made of epitaxial graphene grown onto a silicon carbide on silicon substrate, overcomes the major challenges of corrosion, durability and skin-contact resistance.
