ECG Arduino shield
Electromyograph (EMG): It is the electrical activities of the muscle and the nerve cells that control it (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. The signal is shown in figure (3), when muscles are active, they produce an electrical current, this current is usually proportional to the level of the muscle activity. EMG signal.
The signal can be recorded in two different ways; by needles inserted to a single muscle fibre or by electrodes on the skin of the patient to record the whole muscle activities on the body of the patient as shown in figure (4); to active electrodes on top of the tested muscle and one reference electrode between the active electrodes or on other part of the body. EMG electrodes placement.
EMG can be used to translates the muscles activities into graphs, sounds or numerical values that a specialist interprets. EMG results can reveal nerve function, muscle function or problems with the nerve-to-muscle signal transmission.
The aim of the project
Engineers, particularly biomedical engineers are strongly involved in solving many problems related to human body in which they might need to make use of the natural biological signals of the body [like EMG]. Such biological signal requires reliable safe-to-use bio-amplifiers that can integrate with microcontrollers or other digital systems. Upon researching this area a gap was found between the Engineering community and the biomedical engineering problems which can be summarized (safety-cost-reliability-time) The aim of this project is to build low cost safe to use Arduino shields that will help students, lecturers, beginners and developers with no background in electronics and/or programming to get those biological signals in analog form so they can build their projects easily, with high efficiency regarding the size, weight, and outputs
It is a shield that collects the EMG signal from the human skeletal muscles. Amplify it, filter it and output it to the analog pin of the Arduino.
