Graphene Sensors Make It Possible To Control Robots With Your Mind

Scientists have created a 3D-patterned graphene-based sensors capable of measuring brain electrical activity without the usage of conductive gels.

These “dry” sensors, which are used in electroencephalography (EEG) to identify neurological disorders or to control external equipment through brain-machine interfaces, are less irritating and allergic-inducing than traditional “wet” sensors.

When the dry sensors are combined with an augmented reality headset and an elastic headband, a robot can be controlled without using your hands. Even though this isn’t as good as wet sensors, it’s still a step towards making simple, non-invasive brain-machine interfaces.

According to a journal published in ACS Applied Nano Materials, recent research has generated a 3D-patterned electronic headband that can assess the electrical activity of the brain without the need of conductive gels. These “dry” sensors could allow humans to control robots with their minds.

Electroencephalography (EEG), according to the study, employs electrodes implanted in or placed on the surface of the head to monitor electrical impulses from the brain. Using brain-machine interfaces, this technology aids in the diagnosis of neurological issues as well as the operation of external equipment.

Conventional “wet” sensors that are applied to the head conductively may irritate or worsen allergies. Despite the development of “dry” sensors, none have proven to be as effective as wet ones.

Francesca Iacopi and her colleagues developed a 3D graphene-based sensor that can precisely detect brain activity while generating no discomfort.
