18. An artificial-reality system, comprising:
an artificial-reality headset;
a wearable device that is used as an input device for the artificial-reality headset, the wearable device comprising:
a conductive deformable fabric, the conductive deformable fabric comprising:
a first portion of the conductive deformable fabric that includes a first stitch pattern;
a second portion of the conductive deformable fabric, including:
a conductive trace that has a non-extendable fixed length along a first axis;
the conductive trace is sewn into a fabric, wherein:
 the fabric structure includes a second stitch pattern that facilitates the conductive trace to unfold and fold in an oscillating fashion to allow the conductive trace to expand and contract, respectively, along the first axis without exceeding the fixed length of the conductive trace, wherein the second stitch pattern has a looser stitch pattern along the first axis than the first stitch pattern to allow the conductive trace to expand and contract along the first axis, and
 the conductive trace is positioned within the wearable device such that when the wearable device is worn, the first and second stitch patterns are over a joint of the user to allow the first and second stitch patterns to expand or contract along with movement of the joint.
