Abstract: An electroencephalogram electrode includes: a bottom portion on which a connection member is placed, the connection member which is configured to supply a biological signal that is acquired from a subject through conductive gel, to an external apparatus; an annular wall which annularly extends from the bottom portion in a contact direction with respect to the subject; and a plurality of barb members which are disposed in a holding space for the conductive gel that is located inside the annular wall, and which elongate from the bottom portion in the contact direction with respect to the subject.

Abstract: A body electrode unit includes a body electrode and a release sheet to which the body electrode is attached. The body electrode includes a first electrode configured to stimulate a muscle of a body, a second electrode, and a third electrode. The second electrode and the third electrode are configured to detect a physiological signal from the muscle that is stimulated by the first electrode. The body electrode also includes a first connection portion arranged between the first electrode and the second electrode, and a second connection portion arranged between the third electrode and one of the first electrode and the second electrode. The first connection portion has at least one first direction changing part configured to change a direction in which the first connection portion extends, such that at least one of a distance and an angle between the first electrode and the second electrode is adjustable.

Abstract: A defibrillation pad for a defibrillator, includes: a pair of electrode pads (10) each including a gel portion (12); lead wires (21, 22); a pair of nonconductive release liners (30A, 30B) each detachably stuck to the corresponding gel portion (12) and each having a through hole (32A, 32B) opposed to the corresponding gel portion; and a connecting member (40) comprising an electric connecting pattern (41) having a predetermined electrical resistance, wherein the pair of gel portions (12), each of which is exposed from the corresponding through hole (32A, 32B), are electrically connected to each other through the electric connecting pattern (41) in a state where each of the pair of release liners (30A, 30B) are stuck to the corresponding gel portion. The connecting member (40) has a cut region (45) by which the pair of gel portions are electrically disconnected to each other when the pair of electrode pads are stuck to a living body.

Abstract: A gel layer retained in a retaining member 15, such as non-woven fabric, is placed on one side of an electrode element 1. The electrode element 1 is held by a flexible and extendable tape 11, and the tape 11 adheres to a biological surface tissue. When being plastered onto the biological surface tissue, the tape 11 is covered with cover films 12 and 13, thereby preventing occurrence of a kink in the tape 11. After the tape 11 has been attached to the biological surface tissue, a butt-joined portion between two sub-divisions constituting a cover film 12 is exfoliated to the outside, thus preventing removal of the tape 11.
