Wearable electrode array capable of being used for obtaining myoelectric signals of surfaces of arms and legs

Abstract

The invention discloses a wearable electrode array capable of being used for obtaining myoelectric signals of surfaces of arms and legs. The wearable electrode array is used for measuring myoelectric signals of human bodies and comprises an elastic substrate which is worn on one of arms and legs and a plurality of dry electrodes which contact with surfaces of arms and legs. The plurality of dry electrodes are fixed on the elastic substrate and form at least one electrode ring which encircles the elastic substrate, all dry electrodes are led out through electrode leads, distances between any two adjacent dry electrodes are equal in the at least one electrode ring, a myoelectric passage is formed inside surface skin of arms and legs between any two adjacent dry electrodes in the at least one electrode ring, and all myoelectric passages are distributed in a zigzag shape. The wearable electrode array is simple in structure, convenient to manufacture and use and capable of guaranteeing that all dry electrodes contacting with surfaces of arms and legs are not displaced during usage and keeping the consistence of distances between all dry electrodes, so that the difficulty in post processing of myoelectric signals is reduced, and the robustness of a system is improved.

Description

technical field [0001] The invention relates to the technical field of electrical detection of physiological signals, in particular to a wearable electrode array that can be used to acquire surface myoelectric signals of limbs. Background technique [0002] Electrical detection of physiological signals of the human or animal body is one of the commonly used clinical inspection methods at present. Generally, various biopotentials of the human body or animal body are detected by electrodes. Myoelectric signal is the electrical signal that accompanies muscle contraction. Measuring human body's electromyographic signal is an important method to detect muscle activity in vivo. Moreover, EMG signals can be applied to the detection and diagnosis of muscle-related neurological diseases, and can also be used as a human-machine interface for mechanical equipment, artificial limbs, and computer control and operation. [0003] Generally speaking, there are two different methods for col...
