Electronics-In the Hospital for Engineers is a new area for applying technology. The discussion of the Muscle function that follows includes a discussion of the physiology of the nervous system and the peripheral nerves. The bioelectric potentials associated with muscle activity constitute the electromyogram (EMG), which measured at the surface of the body near a muscle of interest. Since most EMG measurements are intended to obtain as indication of the amount of activity of a given muscle or group of muscles, rather than of an individual muscle fiber, the pattern is usually a summation of the individual action potential from the fibers constituting the muscle or muscle being measured. EMG Measurements are important for the myoelectric control of prosthetic devices means artificial limbs. This use involves picking up EMG signals from the muscle at the terminated nerve endings of the remaining limb and using the signals to activate a mechanical arm. This is the most demanding requirement from am EMG since on it depends the working of the prosthetic device. This prosthetic device is further controlled by the use of the advance technologies as by microcontroller in the place between the motor driving circuit and the signal interface with the use of the analog-to-digital controller. Application of this technology is very much useful to the patients of disability of limbs. These signals are used to drive artificial limb according to the signals receiving by the electrodes. There are some new developments are going on the wheelchair which will driven through the movements of the EMG signals.
