Abstract

A multi-electrode type electrocardiographic electrode structure includes a base member made of non-woven cloth, electrode and lead sections formed by using a liquid conductor printed on or impregnating the base member, the electrode section consisting of a plurality of electrodes arranged on the base member, the lead section being connected to the individual electrodes, an electrolyte material provided on the electrodes and serving to reduce the resistance of the skin of a living body, and an insulating adhesive material provided on the base member to alternate with the electrodes for permitting the electrocardiographic electrode structure to be held in close contact with the living body.

Claims

1. A multi-electrode type electrocardiographic electrode comprising:

a base member made of non-woven cloth;

a plurality of electrodes and leads provided on said base member;

said electrodes and leads being integrally formed by printing on or impregnating said base member within a liquid conductor, said leads being connected to individual electrodes;

an electrolyte material provided on said electrodes and serving to reduce the resistance of the skin of a living body; and

an insulating adhesive material layer provided on said base member to alternate with said electrodes whereby said electrocardiographic electrode structure is held in close contact with the skin of the living body.

2. A multi-electrode type electrocardiographic electrode according to claim 2, further comprising an insulating layer connected to said base member at a surface opposite to that including electrode and lead sections.

3. A multi-electrode type electrocardiographic electrode comprising:

a base member made of non-woven cloth;

a plurality of electrodes disposed on a first surface of said base member;

an insulating layer having a plurality of portions with one side disposed on said first surface of said base member said portions alternating with said electrodes;

a plurality of leads connected to individual electrodes;

said electrodes and leads being integrally made of a liquid conductor printed on or impregnating said base member;

an adhesive layer having a first side disposed on an opposite side of each of said portions of said insulating layer;

a plurality of electrolyte material members, each disposed over one of said electrodes and having ends partially overlapping said adhesive layer with parts of said adhesive layer being exposed for adhering to the skin of a living body.

4. A multi-electrode type electrocardiographic electrode according to claim 3, further comprising an insulating layer connected to a second surface, opposite said first surface of said base member.
