Wearable device capable of measuring eeg and ecg for long time

Abstract

A wearable device comprises a sensor unit and a control unit. The sensor unit: includes a plurality of electrodes which are mounted on the head of a user above the cervical portion and acquire electrical signals from the head; acquires an electroencephalogram of the user on the basis of the difference between the electronic signals acquired by two of the plurality of electrodes; and acquires an electrocardiogram of the user on the basis of the difference between the electrical signals acquired by two other electrodes among the plurality of electrodes. The control unit is electrically connected with the sensor unit, and converts, into digital signals, the analog signals of the electroencephalogram and electrocardiogram acquired by the sensor unit.
