Abstract
A wearable EEG monitor for continuously monitoring the EEG of a user through capacitive coupling to an ear canal of a user includes an ear insert () for positioning within the human ear canal, having at least two capacitive electrodes () for recording a signal. The electrodes are coated with a dielectricum for electrical insulation. The electrodes are connected to an amplifier (). The amplifier has an input impedance matched to the impedance of the electrodes. The invention further provides a method of monitoring brain waves.
