GARMENTS HAVING STRETCHABLE AND CONDUCTIVE INK
First Claim
1. 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 μ
m, 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.

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.
