Strain-locking knit band structures with embedded electronics for wearable devices

A band-wearable device, comprising:

• a softgood comprising:
• a fabric constructed using a knit pattern, and the fabric being configured to elongate along an axis, such that:
• the fabric is configured to give up its mechanical slack that exists as a result of the knit pattern, whereby giving up the mechanical slack causes the fabric to be extended up to a length along the axis;
• and
• the fabric is also configured to resist stretching to a longer length after the fabric has been extended up to the length along the first axis, wherein:
• the resistance to stretching is provided by fibers of the fabric, and
• a tension force required to overcome the resistance to stretching the fabric is greater than a force required to cause the fabric to give up its mechanical slack;
• and
• an embedded conductive trace configured to have a maximum operating length that is at least equal to the length.

An artificial reality system, comprising:

• an artificial reality headset;
• a wearable device, wherein:
• the wearable device is in communication with the artificial-reality headset, and
• the wearable device includes a softgood, wherein the softgood is comprises:
• a fabric constructed using a knit pattern, and the fabric being configured to elongate along an axis, such that:
• the fabric is configured to give up its mechanical slack that exists as a result of the knit pattern, whereby giving up the mechanical slack causes the fabric to be extended up to a length along the axis;
• and
• the fabric is also configured to resist stretching to a longer length after the fabric has been extended up to the length along the first axis, wherein:
• the resistance to stretching is provided by fibers of the fabric, and
• a tension force required to overcome the resistance to stretching the fabric is greater than a force required to cause the fabric to give up its mechanical slack;
• and
• an embedded conductive trace configured to have a maximum operating length that is at least equal to the length.
