Intelligent fitness and sports mouthguard

An intelligent mouthguard system, comprising:

• a mouthguard and an external processing unit;
• the mouthguard including:
• a nine-axis inertial sensor comprising a three-axis magnetometer, a three-axis accelerometer and a three-axis gyroscope, the three-axis magnetometer configured to provide a reference plane in relation to earth's magnetic field for the three-axis accelerometer and the three-axis gyroscope;
• an internal module in communication with the nine-axis inertial sensor, the internal module comprising a microprocessor configured to store sensor data corresponding to the three-axis magnetometer, the three-axis accelerometer and the three-axis gyroscope in memory of the mouthguard and a transceiver configured to transmit the stored sensor data to the external processing unit when the mouthguard is located in an oral cavity, the stored sensor data transmitted in response to a transmission request received from the external processing unit communicatively coupled to the mouthguard;
• and
• an infrared (IR) sensor, wherein blood pressure can be determined based upon sensor data from the IR sensor when the mouthguard is located in the oral cavity.
