BRAIN WAVE MEASURING ELECTRODE, CAP WITH BRAIN WAVE MEASURING ELECTRODE AND BRAIN WAVE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a brain wave measuring electrode surely coming come into contact with a scalp through a space between hairs to secure conduction without applying excessive pressure to the scalp, and to provide a cap with the brain wave measuring electrode and a brain wave measuring device.SOLUTION: A brain wave measuring electrode includes: a chip part abutted on a measuring object to receive an electric signal from the measuring object; and a signal transmitting part for receiving the electric signal from the chip part and transmitting the same to a signal processor. A surface of the chip part that abuts on the measuring object is provided with a projection having conductivity, flexibility and elasticity. In addition, the projection is formed of metal material with conductivity and the projection has a stretching property by being energized by an elastic member in the vertical direction to a contact surface with the measuring object.
