- n. a medical instrument that records the electrical waves associated with the activity of skeletal muscles
Such devices may include an electromyograph (EMG), which monitors muscle tension, an electroencephalograph (EEG), which monitors brain waves, or a heart monitor.
The user controlling the "hand" wears a wristband-like electromyograph sensor, which causes the robotic appendage to react according to muscle contractions.
These signals are picked up by a sensor called an electromyograph worn like a watch on the forearm of the person making the movements.
