- a biosignal measuring device is the biosignal measuring device according to Embodiment 16, wherein the substrate is made of a flexible, electrically insulating material.
- a biosignal measurement electrode according to Embodiment 22 is the biosignal measurement electrode according to any one of Embodiments 3, 4, 5, 6, and 9 to 11, wherein the plurality of regularly arranged
- the arrangement of the electrode installation sites is two in the first row, three in the second row, four in the fourth row, and three in the fifth row.
- the distance between the electrode installation site and the electrode installation site immediately adjacent to the electrode installation site is the same, and the distance is between 0.5 cm and 2 cm.
- each drawing is a schematic diagram and is not necessarily strictly illustrated. Duplicate descriptions in each drawing are omitted or simplified.
- the material of the substrate may be a flexible material.
- the material of the substrate may be a hard material.
- the hard material is, for example, hard plastic.
- a substrate having a shape corresponding to the surface portion of the body to be measured, for example, the surface shape of the mandible when measuring the electromyogram of the suprahyoid muscle group, is formed of hard plastic, and the above electrodes are attached to the substrate.
- a structure in which an installation site is arranged and an electrode is installed in the electrode installation site is also a biological signal measurement electrode according to the present invention.
- the electrodes are arranged as shown in FIGS.
- muscles sometimes exist in layers in the depth direction from the surface of the body, and some of them extend in different directions on a plane.
- electromyograms of a plurality of muscles it is necessary to arrange a plurality of electrodes used for measurement along the muscle fibers of the muscles to be measured. , are advantageously arranged at reasonably short intervals.

Abstract
Les problèmes suivants surviennent lors de la détection de signaux électriques, générés dans un corps vivant, par la mise en contact d'une électrode avec une surface de corps vivant. (1) Le contact électrique entre une électrode ayant une surface de contact plane et la peau n'est pas maintenu. (2) Dans le cas d'une électrode en forme de substrat dans laquelle un grand nombre d'électrodes sont disposées sur un substrat, il est difficile de mesurer simultanément les muscles qui sont disposés en couches et s'étendent dans de multiples directions. (3) Des électrodes individuelles dans une électrode en forme de substrat sont fixées et ainsi limitées en termes d'utilisation. (4) Il est difficile d'utiliser une électrode en forme de substrat lorsque la partie de la surface du corps vivant sur laquelle l'électrode est disposée présente une grande courbure. Les moyens suivants ont été utilisés pour résoudre ces problèmes. (1) La surface de contact entre l'électrode et le corps vivant a été rendue convexe. (2) Un agencement des électrodes a été conçu. (3) Des électrodes individuelles ont été fabriquées pour pouvoir être facilement attachées et détachées. (4) L'électrode en forme de substrat a été pressée par un coussin.
