Description Baby IntroductionBy detecting electromyogram (EMG), measuring muscle activity has traditionally been used in research, but with shrinking but powerful microcontrollers and integrated circuits, EMG Road and sensors can be used for various control systems. The sensor will measure filtering, rectifying electrical activity in the muscle output 0- volt, the output size to take Depending on the amount of muscle activity is.
