Abstract
An electrode of an embodiment of the present disclosure includes: a substrate on which an electrical circuit is mounted; a first electrode unit disposed on the substrate and electrically coupled to the electrical circuit; and a second electrode unit having conductivity and elasticity and in which at least a part of the first electrode unit is embedded, the second electrode unit being to be brought into contact with a living body.
Claims15
A biopotential measurement electrode, comprising:
- a substrate having a first axial or longitudinal surface and a second axial or longitudinal surface opposite the first axial or longitudinal surface;
- an electrical circuit disposed directly on the first axial or longitudinal surface of the substrate;
- a first electrode unit formed of a material having conductivity, wherein the first electrode unit is disposed on an entirety of the second axial or longitudinal surface of the substrate and is electrically coupled to the electrical circuit;
- and
- a second electrode unit having a first axial or longitudinal axial surface and a second axial or longitudinal surface opposite the first axial or longitudinal surface of the second electrode unit, wherein:
- the second electrode unit is formed of a material having conductivity and elasticity;
