Abstract

La présente invention concerne des vêtements pouvant mesurer avec précision, en tant qu'informations biologiques, à la fois les signaux électriques d'un corps et l'état respiratoire de celui-ci.　Ce vêtement de mesure d'informations biologiques comprend un tissu avant, une électrode de mesure électrocardiographique qui est fournie à la surface côté peau du tissu avant, et un capteur extensible qui est fourni à la surface du tissu avant sur le côté opposé de la surface côté peau. La position du point le plus bas du capteur extensible, dans le sens de la longueur du tissu avant, est plus élevée que la position du point le plus haut de l'électrode de mesure électrocardiographique.
