A novel carbon-based biosensor developed at the University of Technology Sydney (UTS) is set to drive new innovations in brain-controlled robotics.
Developed by Professor Francesca Iacopi and her team in the UTS Faculty of Engineering and IT, 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 then be translated into commands to control autonomous robotic systems.
A study of the biosensor is published in the Journal of Neural Engineering this month.
The sensor is made of epitaxial graphene — essentially multiple layers of very thin, very strong carbon — grown directly onto a silicon carbide on silicon substrate. The result is a highly scalable novel sensing technology that overcomes three major challenges of graphene-based biosensing: corrosion, durability and skin-contact resistance.
