Abstract

The study aimed to create a reliable wearable strain gauge sensor suited for a mechanomyography measurement of 2 arm muscles. The mechanomyography was developed to act as a complementary means of muscle activation measurement to electromyography. The sensor for the mechanomyography was a thread sensor made of cotton thread dipped in a multi walled carbon nanotubes dispersion. The fabricated sensor has a negative gauge factor, which means the resistance decreases as it is given strain. The sensor then sewn on an arm sleeve to conform to the subject’s arm. The best sewing pattern for the sensor is 1 cm of length with 3 meanders, which produces the highest sensitivity at -1.47 of gauge factor. The sensor then connected to a voltage divider to translate the resistance change to a voltage signal, then converted to force change. The final setup for the device utilized two different sensors to simultaneously read the biceps and the triceps brachii. The device then tested on 5 male subjects, falling between the inclusion group. The developed mechanomyography was able to plot the activation of the both muscles.
