Abstract
Methods of forming garments having one or more stretchable conductive ink patterns. Described herein are method of making garments (including compression garments) having one or more highly stretchable conductive ink pattern formed of a composite of an insulative adhesive, a conductive ink, and an intermediate gradient zone between the adhesive and conductive ink. The conductive ink typically includes between about 40-60% conductive particles, between about 30-50% binder; between about 3-7% solvent; and between about 3-7% thickener. The stretchable conductive ink patterns may be stretched more than twice their length without breaking or rupturing.
Claims29
A wearable electronics device, the device comprising:
- a garment comprising a fabric;
- and
- at least one conductive ink pattern on the garment, wherein the conductive ink pattern comprises:
- a layer of conductive ink having:
- between about 40-60% conductive particles, between about 30-50% binder;
- between about 3-7% solvent;
- and between about 3-7% thickener;
- a layer of an elastic adhesive on the garment;
- and
- a gradient region between the conductive ink and the adhesive having a thickness of greater than about 10 μm, the gradient region comprising a nonhomogeneous mixture of the conductive ink and the adhesive wherein the concentration of conductive ink decreases from a region closer to the layer of conductive ink to the layer of elastic adhesive.
A wearable electronics device, the device comprising:
- a garment comprising a compression fabric;
- and
- at least one stretchable and conductive ink pattern on the garment having a sheet resistivity of less than about 10 Kohms/square, wherein the conductive ink pattern is stretchable up to at least about 100% without breaking, and comprises:

- a gradient region greater than about 10 μm between the conductive ink and the adhesive, the gradient region comprising a nonhomogeneous mixture of the conductive ink and the adhesive wherein the concentration of conductive ink decreases from a region closer to the layer of conductive ink to the layer of elastic adhesive;
- and
- an insulating resin over at least a portion of the layer of conductive ink.
