1. A wearable article, comprising:
a flexible support;
at least one sensor for measuring a physiological parameter of a wearer of the wearable article;
at least one 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,
wherein the at least one electrically conductive yarn comprises:
an assembly of at least two resistive elements, wherein each resistive element comprises a metal-coated elastic core; and
a wrapping layer covering the assembly of the at least two resistive elements,
wherein the at least one sensor comprises an electrode having a flexible conductive matrix, and the at least one electrically conductive yarn is connected to the flexible conductive matrix by sewing,
the wearable article further comprising an electronic board attached to the flexible support, wherein the electronic board has a conductive edge portion, holes are provided in the conductive edge portion, and the at least one electrically conductive yarn is connected to the electronic board by sewing to the conductive edge portion through at least one of the holes.
