Fully reconfigurable modular body-worn sensors

A method comprising:

• detecting, by one or more electroencephalography (EEG) sensor nodes in a fully reconfigurable sensor network, electrical signals indicating activity of a brain of a subject, each EEG sensor node embodying an analog front end (AFE) circuit;
• and
• transmitting, from the one or more EEG sensor nodes, signal information relating to the detected electrical signals to a centralized command control node (CCN) in the sensor network configured to perform a processing technique on the transmitted information,
• wherein the one or more EEG sensor nodes detect the electrical signals without a driven right leg (DRL) circuit in the sensor network.

A method comprising:

• receiving, at a centralized command control node (CCN) in a fully reconfigurable sensor network, signal information relating to electrical signals indicating activity of a brain of a subject detected by one or more electroencephalography (EEG) sensor nodes in the sensor network, each EEG sensor node embodying an analog front end (AFE) circuit;
• and
• performing, by the CCN, a processing technique on the received information resulting in processed signal data,
• wherein the one or more EEG sensor nodes detect the electrical signals without a driven right leg (DRL) circuit in the sensor network.
