Problems solved by technology
[0004] In order to ensure a stable electrical signal even when these electrodes are active, the adhesion of the electrodes to the skin is important. However, if you want to integrate these electrodes with clothing, the biological electrodes will be stressed when they are repeatedly put on and taken off and washed. It is difficult to treat it in the same way as ordinary clothes in terms of convenience because of the possibility of electrode disconnection or detachment from clothing due to deformation and deformation.

Abstract
[Problem] To provide a stretchable layered sheet for a garment for biological information measurement, the sheet having excellent electroconductivity and stretchability, acquiring electrical signals in a stable manner, having improved adhesiveness to a substrate, and being free of electrode peeling or wire breaking when subjected to the stress and deformation occurring during dressing / undressing and laundering. [Solution] This stretchable layered sheet is characterized by: being constituted of at least two layers, a stretchable insulating layer and a stretchable conductor layer, both having adhesiveness; and by having a 90 degree peeling strength between the stretchable insulating layer and stretchable conductor layer of 1.0 N / cm or greater.
Description
technical field [0001] The present invention relates to stretchable conductors and insulating films thereof that can be used in electrical wiring and electrodes used in clothing for measuring physiological information, for example, the comfort that can measure weak electrical signals inside living things by contacting with the skin surface of living things Excellent clothing for physiological information measurement can be used as a stretchable laminated sheet for its electrodes and electrical wiring. Background technique [0002] Conventionally, in order to measure weak bioelectrical signals inside living organisms such as brainwaves, electrocardiograms, and electromyograms, sticky bioelectrode sheets made of conductive soft conductive adhesive gel or the like have been used (Patent Document 1) etc., this kind of viscous electrode sheet is sticky to the skin, the subject can ensure the conductivity in a quiet state, and there will be no noise or signal degradation in the bi...
