Abstract
A biological signal detection electrode includes an electrode element and a plurality of drought-resistant electrolytic solution soaking parts. The electrode element is made of a conductive material and has a surface. The plurality of drought-resistant electrolytic solution soaking parts are placed at predetermined intervals on the surface of the electrode element, are formed to have a thickness that allows contact with a scalp without hair being sandwiched between the electrode element and the scalp, and are soaked in a drought-resistant electrolytic solution including a drought-resistant liquid and a conductive liquid.
Claims6
A biological signal detection electrode comprising:
- an electrode element that is made of a conductive material and has a surface;
- a plurality of drought-resistant electrolytic solution soaking parts that are placed at predetermined intervals on the surface of the electrode element, are formed to have a thickness that allows contact with a scalp without hair being sandwiched between the electrode element and the scalp, and are soaked in a drought-resistant electrolytic solution including a drought-resistant liquid and a conductive liquid;
- and
- a support part that is formed to have an almost the same height as the plurality of drought-resistant electrolytic solution soaking parts, has through holes on a surface with an area larger than areas of the plurality of drought-resistant electrolytic solution soaking parts, into which the plurality of drought-resistant electrolytic solution soaking parts are inserted, and shrinks by the thickness of the hair sandwiched between the plurality of drought-resistant electrolytic solution soaking parts and the scalp of the test subject when ends of the plurality of drought-resistant electrolytic solution soaking parts opposite to a side of the electrode element are pushed against the scalp of the test subject with a predetermined pushing force in the state where the plurality of drought-resistant electrolytic solution soaking parts are inserted into the through holes.
