System and method for interpretation of signal-to-noise ratios detected in an array of electrodes sensors in terms of physical and cognitive state

A system for measuring the cognitive state of an individual, comprising:

• an array of electrocardiogram (ECG) sensors placed in contact with the individual, where the ECG sensors continually measuring the ECG voltage and related signal-to-noise ratio for each ECG sensor of the array;
• and
• a microprocessor that receives the signal-to-noise ratio from each ECG sensor, where the microprocessor,
• calculates a distance to each ECG sensor and pressure applied to each ECG sensor that corresponds to the ECG voltage and signal-to-noise ratio measurements,
• generates a graphical distance and pressure map based on the combined signal-to-noise ratios of the ECG sensors, where the graphical distance and pressure map uses color coding to indicate relative values of the combined signal-to-noise ratios, and
• continually analyzes the distance and pressure map to detect high amplitude and repeated irregular patterns that indicate a fatigued cognitive state of the individual.
