Design of a Smart Wearable Armband for Real Time Detection of Localized Muscle Fatigue using sEMG Signals

Muscle fatigue is a problem for people who play
sports, are recovering from injuries, and perform physical
work. It makes muscles weaker and more likely to get injured.
This paper presents a wearable armband designed to detect
localized muscle fatigue in real time. The armband uses surface
electromyography (sEMG) to identify fatigue conditions. It is
built using an ESP32 microcontroller along with sensors that
monitor muscle activity. When fatigue is detected, the system
activates vibration therapy to assist muscle recovery. The
device can be controlled through a mobile application.
Experimental evaluation showed that the system can detect
muscle fatigue with an accuracy of over 92%. The armband is
compact, cost-effective, and easy to use, making it suitable for
continuous muscle monitoring and rehabilitation support.
