1. A system comprising:
a set of low-profile EEG sensors, each comprising an array of flexible epidermis-penetrating microneedle electrodes fabricated on a flexible-circuit substrate, the flexible-circuit substrate operatively connected to an analog-to-digital converter circuitry operatively connected to a wireless interface circuitry; and
a brain-machine interface operatively connected to the set of low-profile EEG sensors, the brain-machine interface comprising:
a processor; and
a memory operatively connected to the processor, the memory having instructions stored thereon, wherein execution of the instructions by the processor causes the processor to:
receive EEG signals acquired from the low-profile EEG sensor;
continuously classify brain signals as control signals via a trained neural network from the acquired EEG signals; and
output the control signals to a virtual reality environment controller to actuate a command in a VR scene generated by the virtual reality environment controller to be viewed by a subject.
