System and method for real-time personnel fatigue level monitoring

A shoe for monitoring fatigue level of a subject, comprising:

• a shoe sole disposing a plurality of sensors therein;
• a micro-controller communicatively connecting to said plurality of sensors and configured to receive readings of said plurality of sensors, and is further configured to validate the readings of a first sensor of the plurality of sensors with readings of a second sensor, wherein the first sensor of the plurality of sensors is a ball tilt sensor configured to detect orientation of the subject to generate first sensor data and the second sensor is an accelerometer to generate second sensor data used to reduce an error in the first sensor data;
• and
• a wireless interface communicatively connecting to said micro-controller and configured to send the readings of said plurality of sensors wirelessly to a base station, wherein said base station determines the fatigue level of the subject based on at least a portion of the readings of said plurality of sensors transmitted by e wireless interface.

A method for monitoring fatigue level of a subject using a shoe having a sole, said shoe comprising a plurality of sensors embedded in the shoe sole;

• a micro-controller connecting to said plurality of sensors and is configured to validate the readings of a first sensor of the plurality of sensors with readings of a second sensor, wherein the first sensor of the plurality of sensors is a ball tilt sensor configured to detect orientation of the subject to generate first sensor data and the second sensor is an accelerometer to generate second sensor data used to reduce an error in the first sensor data;
• and a wireless interface connecting to said micro-controller, said method comprising the step of:
• receiving, by said micro-controller, readings of said plurality of sensors;
• sending, by said wireless interface, the readings of said plurality of sensors wirelessly to a base station;
• and
• determining, by said base station, the fatigue level of the subject based on the reading of said plurality of sensors.
