Myoelectric NI ELVIS Controls Device—The Quanser QNET Myoelectric Board for NI ELVIS II/II+ is an add-on application board for the NI Engineering Laboratory Virtual Instrumentation Suite II (NI ELVIS II) or NI ELVIS II+. This device has been developed for education to facilitate hands-on, active learning of the fundamentals of biomedical signals and controls. Through experiments based on the principles of electromyography (EMG), students learn to control a servo motor to learn topics like the contraction of muscles. EMG applications include myoelectric prosthetics, bioinstrumentation, diagnostic evaluation of muscle and nerve disorders, assisted control in wheelchairs, and unvoiced speech recognition.
