[0025] 1. Implementation method

[0026] 2. Other implementation methods

[0027]

[0028] [1. Electrode structure]

[0029] figure 1 An electrode 1 according to an embodiment of the invention is shown. The electrode 1 includes an electrode element 2 , an anti-drying electrolyte impregnated part 3 , a support part 4 and a wire 5 .

[0030] The electrode member 2 is made of a highly conductive material such as gold, and is formed roughly in a disc shape, and a wire 5 is connected to a predetermined position on the side of the original disc shape.

[0031] Such as figure 2 and image 3 As shown, the anti-drying electrolyte impregnation portion 3 is formed approximately in a cylindrical shape with a diameter of approximately 2 mm and a length of approximately 10 mm, and an end portion 3A opposite to the electrode element 2 side is approximately hemispherical. In the anti-drying ele...

Abstract

The invention provides a biological signal detection electrode and a biological signal detection apparatus, wherein the 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.

Description

technical field [0001] The present invention relates to a biosignal detection electrode and a biosignal detection device that are preferably applied when, for example, brain waves are obtained as electronic signals. Background technique [0002] There have been prior art devices that obtain brain waves from many electrodes provided on a headgear or the like and in contact with the scalp of a test subject wearing the headgear. [0003] Due to differences in the presence of hair and head shape between individuals, the electrodes of the device were attached to the scalp using a conductive paste. [0004] Therefore, the device causes troublesome work such as attaching many electrodes to the scalp, and washing the hair to remove the slurry. [0005] Japanese Unexamined Patent Application Publication Nos. 2006-6666 and 2006-34429 and the like propose electrodes in which an elastic member immersed in a conductive liquid of physiological saline or a mixture of physiological saline ...
