Biosignal measurement device
First Claim
1. A biosignal measurement device for measurement of a biosignal in a head, comprising:
- a support configured to attach to the head;
a plurality of depressions in a surface of the support at first intervals;
a plurality of electrodes in the plurality of depressions;
a plurality of grooves at second intervals in a lengthwise direction of the support; and
an adjuster section configured to slide in the lengthwise direction of the support,wherein at least one of the plurality of electrodes includes a substrate and a plurality of conductive fibers,wherein an end of conductive fiber of the plurality of conductive fibers is fixed to a surface of the substrate, wherein each conductive fiber of the plurality of conductive fibers is orthogonal to the surface of the substrate, andwherein a portion of an inner surface of the adjuster section facing the plurality of grooves is provided with a claw configured to fit in each groove of the plurality of grooves.

Abstract
A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects.
A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.
