The present device is directed to a biometric electromyography (EMG) sensor device and methods for using the same to provide a user with the ability to monitor physical muscle fatigue and protect themselves against injury due to overuse. Embodiments of the present disclosure include an accelerometer for artifact noise removal and an EMG sensor that is used to collect EMG signals and surface EMG (sEMG) signals from electrodes placed onto a wearable device, which can be in tight contact with the skin due to its elasticity. This collected data can then be transmitted to an electronic device via a microcontroller. The electronic device may include an app that is continuously running to monitor user fatigue in real-time.
