[0088] [1-1. Structure of biosignal measurement device]

[0089] figure 1 The structure of the biological signal measurement device 1 is shown. The biological signal measurement device 1 has a support portion (hereinafter, also referred to as a hair band) 2 that can be supported on the head. The hair band 2 is made of plate-like plastic material or elastic metal material, and is formed into a C shape.

[0090] A non-slip section 11 made of a material such as rubber is provided at one end of the hair band 2 . The non-sliding portion 11 is bent at the distal end so that the head can be prevented from being stabbed.

[0091] On the other hand, the reference electrode 12 is provided at the other end of the hair band 2 . Such as figure 2 As shown, the reference electrode 12 includes a portion (hereinafter, ...

Abstract

Disclosed is bio-signal measurement equipment which makes it possible to improve measurement accuracy without imposing an excessive burden on the subject. The bio-signal measurement equipment is employed for measurement of bio-signals in the head and includes a support body capable of supporting the head and electrodes provided on the support body. An electrode is provided with a plurality of teeth constituted by: annular portions comprising a pair of annularly-formed conductive wires; and rod-shaped portions formed in the shape of rods by winding the wires of each pair in opposite directions. One end of the rod-shaped portions in the plurality of teeth is directly or indirectly fixed to the support body.

Description

technical field [0001] The present invention relates to a biological signal measuring device, and is suitable for the technical field of acquiring waves generated and propagated in a living body as electric signals and the like. Background technique [0002] It is becoming increasingly apparent that a reduction in the quality or quantity (time) of sleep increases the risk of various lifestyle-related diseases, including circulatory disorders, such as myocardial infarction and cerebral infarction, or endocrine disorders, such as ,diabetes. Furthermore, the prolongation of REM (rapid eye movement) sleep or its decrease in intensity is strongly suspected to be the cause of depression. Since sleep is thus associated with many diseases and social problems that modern man suffers from, the importance of assessing sleep quality will continue to grow in the days to come. [0003] Incidentally, polysomnography is considered a method of assessing sleep. Furthermore, there has been ...
