Abstract

A biosignal measurement device includes an electrode and a signal processing member. The electrode includes an insulation sheet having a hole, a device contact portion provided on the top surface of the insulation sheet and a body contact portion provided on the bottom surface of the insulation sheet, the device contact portion and the body contact portion electrically connected to each other via the hole. The signal processing member includes an externally exposed terminal to make surface contact with the device contact portion, an analog signal processing unit, an A/D signal converter and a digital signal processing unit. Also, the device contact portion and the body contact portion are formed of a material which is both conductive and adhesive. Accordingly, the signal processing member may be directly attached. Noise may be reduced. Also, a biosignal may be accurately measured.
