1. A textile-based electrode, comprising:
- a first fabric portion defining a fabric plane and comprising;
(a) non-conductive yarns; and
(b) at least one electrically conductive region in the fabric plane comprising electrically conductive yarn filaments, said region forming at least one graduated pattern having at least one graduated end that changes gradually or by degrees, the graduated pattern being formed from multiple knit courses of a circular knit in which a first course produces a first length and a second course produces a second length that is different from the first length.

Abstract
Textile-based electrodes incorporating graduated patterns include a fabric portion having non-conductive yarns and an electrically conductive region having electrically conductive yarn filaments. The electrodes can further include float yarns and can be configured in a textured or ribbed construction. When incorporated into a garment, the electrodes can be used to monitor biophysical characteristics, such as the garment wearer'"'"'s heart rate.

12. A method for reducing needle wear when forming textile-based electrodes, comprising:
-
programming a knitting machine to produce a fabric with at least one graduated pattern; forming the graduated pattern by knitting the fabric with electrically conductive yarns or fibers to form at least one electrically conductive region having the graduated pattern of multiple knit courses in which a first course produces a first length, a second course adjacent to the first course produces a second length that is different from the first length, and a third course adjacent to the second course produces a third length that is different from the second length; and knitting the fabric with nonconductive yarns or fibers to form nonconductive portions of the fabric. - View Dependent Claims (13, 14)

15. A textile-based electrode system, comprising:
at least a first fabric portion and a second fabric portion;
the first fabric portion comprising at least a first electrically conductive region with at least one first graduated pattern;
the second fabric portion comprising at least a second electrically conductive region with at least one second graduated pattern that may be the same as or different from the at least one first graduated pattern;
wherein the first and second fabric portions at least partially overlap one another; and
wherein the electrically conductive region of the first fabric portion and the electrically conductive region of the second fabric portion are electrically coupled.- View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
