Description

technical field [0001] The invention belongs to the field of equipment for measuring human body electrical impedance, and in particular relates to a flexible electrode for measuring muscle impedance and a preparation method thereof. Background technique [0002] Electromyography (Electromyogram, EMG) is currently the mainstream method for detecting neuromuscular abnormalities. EMG generally evaluates the function of the neuromuscular system by measuring the conduction of action potentials inside and outside the neuromuscular cell membrane. However, there are limitations to the EMG testing method. First of all, it is very difficult to judge whether the motor unit action potential (MotorUnitActionPotential, MUAP) is abnormal in actual measurement, and experienced doctors need to do multiple inspections on the same muscle area. Secondly, the electromyography needle electrode needs to penetrate the skin, and the stimulation intensity is high, so its measurement requires a high...
