Abstract
A stitched sensor including a plurality of threads stitched to a textile in a stitch geometry is described. The plurality of threads includes a conductive thread, and the stitch geometry is configured such that an electrical property of the stitched sensor changes based on at least one of stretching, relaxation, or bending of the textile. Methods for forming a stitched sensor are also described.
Claims21
A system comprising:
- a stitched sensor comprising a plurality of threads stitched to a textile in a stitch geometry, the plurality of threads comprising a conductive thread defining a plurality of loops in the stitch geometry, wherein the stitch geometry is configured such that an electrical property of the stitched sensor changes based on respective locations at which one or more loops of the plurality of loops contact another portion of the conductive thread.
A method comprising:
- forming a stitched sensor by at least stitching a plurality of threads to a textile in a stitch geometry configured such that an electrical property of the stitched sensor changes based on respective locations at which one or more loops of a plurality of loops of a conductive thread contact another portion of the conductive threshold, the plurality of threads comprising a conductive thread defining the plurality of loops in the stitch geometry.
A system comprising:
- a plurality of threads stitched to a textile in a stitch geometry, the plurality of threads comprising a conductive thread and one or more non-conductive threads, wherein the stitch geometry is configured such that an electrical property of the conductive thread changes based on respective locations at which one or more loops of the plurality of loops contact another portion of the conductive thread;
- and
- a sensing unit electrically coupled to the conductive thread in the stitch geometry and configured to sense the change in the electrical property of the conductive thread.
