This paper discusses on the implementation of electromyogram sensor as the biofeedback of the improvised electrical muscle stimulation technology to improve the muscle strength. The paper explains some fundamental of muscle behavior followed by the muscle weakness issues. The techniques of muscle stimulation and the innovative solutions to overcome the problems encountered by the current muscle stimulation techniques are discussed. The project methodology is explained with proper circuit configurations and programming technique. Preliminary works and validation process on the wrist extensor muscle are presented. Finally, the project functionality is examined based on the simulation results that show the system behavior with respect to the muscle contraction reading.
