Problems solved by technology
[0004] The present invention provides a bioelectrical signal collection and electrical stimulation device, which is used to solve the problem of using wet electrodes in high-density systems in the prior art, which requires repeated addition of conductive glue to a large number of electrodes, and the work efficiency is low. It is easy to short-circuit between the electrodes, which leads to inaccurate identification, and realizes the acquisition and electrical stimulation of the target bioelectric signal at multiple points. It is suitable for high-density body surface electrical signal acquisition and electrical stimulation, and can improve the acquisition and electrical stimulation. Efficiency and accuracy of electrical stimulation

Description
technical field [0001] The invention relates to the technical field of wearable devices, in particular to a bioelectrical signal collection and electrical stimulation device. Background technique [0002] Body surface bioelectrical signals can reflect a variety of physiological, psychological and pathological information of organisms, so the collection of body surface bioelectrical signals has important clinical significance. Electrical stimulation of organisms on the body surface can realize medical and human-computer interaction scenarios such as neural function regulation and tactile simulation. Non-implantable body surface electrodes are the best choice for most clinical and research scenarios due to their safety and convenience. Electrophysiological signals on the surface of the body represented by brain waves (EEG) are usually weak in amplitude, so the contact impedance between the electrode and the skin needs to be kept low to obtain a high signal-to-noise ratio. ...
