Armband to turn on/off electrical equipment for patient is the measurement signal from the muscles (Electromyography: EMG) to study and apply to jobs. This document shows education of the technique for detecting and measuring devices, as well as signal amplification and noise reduction. Therefrom, the signal that the above processing with microcontroller to control the operation of Armband to turn on/off electrical equipment for patient. Patient can use the movement of the arm to turn on/off electrical equipment by themselves and can help themselves.
From the experiment, it was found that another noise signal continuously. Due to the signal is low, so it is more easily disturbed signals. From such problems, this document demonstrates the problem and solutions to research further.
