Embodiment Construction

[0032] Embodiments of the present invention will be described with reference to the drawings.

[0033]

[0034] figure 1 is a schematic structural diagram of an embodiment of the pressure-sensitive conductive yarn of the present invention. Such as figure 1 As shown, the pressure-sensitive conductive yarn 1 is formed by doubly winding wrapping yarns 4, 6 on a core yarn 2, wherein the core yarn 2 consists of an elastic yarn such as polyurethane. The winding direction of the first overwrapping yarn 4 is opposite to the winding direction of the second overwrapping yarn 6 . The manufacturing method of the pressure-sensitive conductive yarn 1 is the same as that of known double-covered yarns.

[0035] The winding yarns 4, 6 are blended yarns of conductive fibers (eg stainless steel fibers) and non-conductive fibers (eg polyester fibers). For example, those yarns described in Japanese Unexamined Patent Publication No. 2003-20538 are preferably used. When a large value of tensi...

Abstract

An object of the present invention is to provide a pressure-sensitive conductive yarn capable of detecting different biological information simultaneously when used as an electrode. A pressure-sensitive conductive yarn comprising a core yarn formed of an elastic yarn around which a winding yarn having conductivity is wound, wherein the winding yarn is a mixed yarn of a conductive fiber and a nonconductive fiber to cause variations in its electrical resistance with elongation or contraction. The invention also provides a biological information-measuring garment.

Description

technical field [0001] The invention relates to a pressure-sensitive conductive yarn and a garment for measuring biological information. Background technique [0002] Biological information, such as respiration, heart rate, etc., are important indicators for determining health status. However, the known measurement of biological signals requires the use of gel to attach electrodes, wrap breathing belts, etc., resulting in a great sense of restraint on the body. [0003] In order to eliminate this sense of restraint and facilitate daily health management, some attempts have been made to detect biological information in a natural state by mounting electrodes on clothing. For example, Patent Document 1 discloses that electrodes formed of conductive yarns are provided on clothes to detect pulse signals. [0004] Patent Document 1: Japanese Unexamined Patent Publication No. 2005-525477 Contents of the invention [0005] The technical problem that the present invention solves...
