In a study in the journal Neuron, scientists describe a new high data-rate, low-power wireless brain sensor. The technology is designed to enable neuroscience research that cannot be accomplished with current sensors that tether subjects with cabled connections.
The head-mounted, 100-channel transmitter is only 5 centimeters in its largest dimension and weighs only 46.1 grams, but can transmit data up to 200 megabits a second.
