Dry EEG Sensors Control Army Robots

Brain-machine interface (BMI) technology, for all its decades of development, still awaits widespread use. Reasons include hardware and software not yet up to the task in non-invasive approaches that use electroencephalogram (EEG) sensors placed on the scalp, and because surgery is required in approaches relying on brain implants.

Now, researchers at, the University of Technology Sydney (UTS), Australia, in collaboration with the Australian Army, have developed portable, prototype dry sensors that achieve 94 percent of the accuracy of benchmark wet sensors, but without the latter’s…
