Description

technical field [0001] The invention relates to the field of biomechanical integration. Background technique [0002] As a commonly used means of muscle movement monitoring, surface electromyography has the advantages of accurate monitoring, non-invasiveness, and low cost. It is widely used in muscle pathological diagnosis, prosthetic control, and neuromuscular physiotherapy rehabilitation. Since the EMG signal is relatively weak, the electrochemical reaction between the electrode and the skin, the impedance change of the electrode-skin interface, and the movement of the electrode often cause large artifact noise. In order to reduce these artifact noise, the EMG electrode should have Stable electrochemical characteristics and electrode-skin impedance, and can be bonded to the skin surface with a certain adhesion. [0003] Transcutaneous electrical stimulation is an electrical stimulation method that lays electrodes on the surface of the human skin to release current to stim...
