Abstract: It is disclosed a composite yarn (1) comprising an electrically conductive yarn (2) and an electrically resistive yarn (3), wherein said electrically conductive yarn (2) is coupled to said electrically resistive yarn (3), and wherein the electrically conductive yarn (2) is electrically insulated from the electrically resistive yarn (3). It is further disclosed a touch sensor (10) comprising at least one composite yarn (1) according to anyone of the previous claims, and a detection device (5) configured to evaluate the capacitance values (CR, CC) of the electrically resistive yarn (3) and of the electrically conductive yarn (2) of said composite yarn (1), said detection device (5) being configured to calculate the ratio (CR/CC) between said capacitance values (CR, CC) of the electrically resistive yarn (3) and of the electrically conductive yarn (2) and to provide an output signal (SOUT) indicative of the location of a touch event along said composite yarn (1) in function of said ratio (CR/CC).

Abstract: A stretchable conductive yarn (1) includes a conductive core (2) of one or more elastic fibers (4-6) and an insulating sheath (3) that covers the conductive core. One or more of the elastic core fibers may be an elastomeric material (4) and may be combined with a less elastic fiber (5, 6) to control the returning properties of the conductive elastic fibers. Also provided are fabrics, garments and various devices formed using the conductive elastic yarns and which can be used to perform various electrical sensing operations to monitor and measure various bodily functions and conditions, or performance of a wearer.
