An elongation sensor, which includes an elastic, electrically insulating core, and at least two resistive elements arranged helically around the elastic core in opposite directions and in contact with each other. A wearable article including a flexible support, at least one elongation sensor arranged on the flexible support so as to have a length varying when a wearer of the wearable article breathes or when muscles of the wearer are contracted or relaxed, and at least one flexible strip arranged on the flexible support. Also, detecting breathing of a subject with the wearable article.

Elongation sensor and wearable article including the elongation sensor

Electrically conductive yarn, which includes an assembly of at least two resistive elements and a wrapping layer covering the assembly of the two resistive elements. Each resistive element includes an elastic core coated with metal. Also, a wearable article including a flexible support, at least one sensor for measuring a physiological parameter of the wearer of the wearable article, at least one of electrically conductive yarn stitched on the flexible support along a path from a respective sensor to a location for an electronic board, and connected to the at least one sensor, and at least one flexible strip attached to the flexible support along the path to protect the at least one electrically conductive yarn.
