Description
Technical Field
The utility model relates to a scalp stimulating electrode technical field especially relates to an open stimulating electrode device and electrode brain electricity cap structure.
Background
Transcranial direct current or alternating current stimulation can change the activity state of the brain to a certain extent, and has important application in various aspects such as brain function research, disease treatment, nerve feedback training and the like. The stimulation electrode is basically composed of a cavernous body, an electrode and a conductive liquid, and the main technical realization mode of the current stimulation electrode is that a certain amount of conductive liquid permeates into the cavernous body, and then the moistened cavernous body and the electrode are assembled into the stimulation electrode. Finally, the assembled stimulating electrode is fixed on the head by using a bandage, an electrode cap and other devices.
Such stimulation electrodes suffer from several disadvantages: 1. the degree of hair wetting with the scalp cannot be visually confirmed. The hair and scalp are covered by the sponge and the electrodes, and the condition that the hair and scalp are wetted by the electrolyte cannot be observed and confirmed, so that the phenomenon that the contact impedance of the electrodes is too high can be caused. 2. The stimulation location and spatial resolution are not high. In order to ensure lower contact impedance of the traditional sponge electrode, the area of the electrode is often larger. Such a large area of electrodes allows the head to simultaneously receive a limited number of electrodes. The coverage area of the electrodes is large, the uncertainty of the distribution of the stimulation current density is also large, and the accurate positioning of the specific stimulated brain area is difficult to realize. 3. The operation mode of injecting liquid first and then placing leads to the extrusion and outflow of electrolyte, thus causing the outflow or short circuit of the electrolyte.
