However, in the “biological signal collection / analysis device” of Patent Literature 1, the position of the ground electrode (irrelevant electrode) is arbitrary, and there is a problem that noise is easily picked up because the shape is large.
[0005]
In Patent Document 2 “Electrocardiographic toilet seat”, electrodes are provided so as to prevent electrification of the toilet seat, but no consideration is given to electromagnetic waves, power supplies and other noise sources.
[0006]
In the "electrocardiogram management device" of Patent Document 3, the handle is used as the ground electrode, and therefore, it is not unrestricted.
[0007]
In Patent Literature 4, “Electrocardiographic measurement toilet seat and a toilet provided with the toilet seat”, electrodes are arranged on the back surface of the toilet seat. Although the seat is made of a conductive material, the seating surface and the electrode are electrically connected, but it is presumed that noise mixing due to charging of the toilet seat is inevitable.
[0008]
Under these circumstances, the present inventors have disclosed a technique relating to heart rate measurement using a toilet seat. (See Non-Patent Document 1)
