Garments having stretchable and conductive ink

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 200% without breaking, and 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;
• a gradient region 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.
