Measuring muscle activity by detecting its electric potential referred to as electromyography EMG has traditionally been used for medical research However with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits EMG circuits and sensors have found their way into all kinds of control systems This sensor will measure the filtered and rectified electrical activity of a muscle outputting 0Vs Volts depending the amount of activity in the selected muscle where Vs signifies the voltage of the power source Its that easy stick on a few electrodes read the voltage out and flex some muscles OR Measuring muscle activation via electric potential referred to as electromyography EMG has traditionally been used for medical research and diagnosis of neuromuscular disorders However with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits EMG circuits and sensors have found their way into prosthetics robotics and other control systems Yet EMG systems remain expensive and mostly outside the grasp of modern hobbyist Electromyography EMG is a method to evaluate motor unit action potential activity in a muscle region As action potentials electrical signals propagate through nerves to neuromuscular junctions the change in electrical potentials voltage can be measured EMG is performed in the clinical setting to diagnose functional abnormalities of muscle in this procedure a needle electrode is inserted directly into a muscle to See Answer
