摘要
A medical appliance for acquiring EEG signals from a patient's head applied solely to the patient's forehead comprising a frontal array of hydrogel electrodes. The appliance also comprises a clear dielectric layer, an electromagnetic shield layer, and signal traces from the electrodes to an appliance connector. The electrodes are generally rectangular in shape and are located at frontal positions according to the International 10-20 System. The electrodes further comprise a retaining mechanism and internal volcano tips to abrade the outer layers of the dermis for improved electrical contact and lower contact impedance.
