Abstract: The nerve weakness detection system is a portable system for detecting nerve and muscle weakness using an EMG sensor, Bluetooth moduleHC-05 , Mobile/System application and ESP32. Conditions such as Peripheral Neuropathy can be identified by analyzing muscle activity signals. The person with peripheral Neuropathy suffers by hand and leg pain and numbness due to the weakness. The EMG sensor captures a raw analog bioelectrical signals from muscles, which are converted into digital form using the ESP32’s built-in signal conversion module(ADC). These signals are processed to evaluate muscle strength and detect abnormalities. The processed data is transmitted to a mobile application via Bluetooth or Wi- Fi, where a weakness index is calculated and displayed in real time using a Mobile/System application. Based on predefined ranges, the system classifies the severity of weakness. This low-cost and user-friendly solution enables early detection, continuous monitoring, and supports rehabilitation, especially in remote healthcare settings.
