Abstract
A method for optimizing contact resistance in electrically conductive yarns and textiles, and textiles having such optimized contact resistance, can include selecting a sensing activity for the textile; selecting a combination of variables from among yarn variables, stitch variables, and textile variables; and knitting an electrically conductive yarn in the textile in accordance with the selected combination of variables, wherein the knitted combination of variables provides an optimal contact resistance in the textile correlated with a desired electrical conductivity for the sensing activity. The knitted combination of variables can provide a predictable yarn contact area for the electrically conductive yarn correlated with the optimal contact resistance.
Claims13
A textile having at least one fully integrated knitted sensor, the textile;
- comprising:
- at least one sensing area adapted for a sensing activity, wherein the sensing activity is selected from the group consisting of:
- tensile force, compressive force, movement, temperature and physiological activity, and wherein the at least one sensing area comprises an electrically conductive yarn knitted in the textile;
- the at least one sensing area comprising a combination of stitches selected from two or more of the group consisting of:
- jersey stitches, miss stitches, and tuck stitches;
- wherein the combination of stitches in the at least one sensing area provides a controllable amount of contact resistance in the textile, and wherein the controllable amount of contact resistance in the textile is correlated with a desired electrical conductivity for the sensing activity.
