石墨烯涂层织物用于可穿戴技术

Graphene—a single layer of carbon atoms arranged in a honeycomb lattice—offers extraordinary conductivity, strength, and flexibility.
When coated onto textiles like polyester or cotton, it transforms fabrics into lightweight, washable sensors and circuits.
Wristbands with graphene traces monitor heart rate and skin temperature continuously without bulky electrodes or adhesive gels.
Its high thermal conductivity helps dissipate heat from wearable batteries, improving safety and battery longevity during extended use.
Researchers embed graphene ink into yarns before weaving, allowing seamless integration into sleeves or collars for gesture control.
Unlike metal wires, graphene coatings resist cracking after hundreds of stretch-and-wash cycles, maintaining signal integrity.
Manufacturing uses scalable techniques like inkjet printing or roll-to-roll coating, keeping costs lower than gold or silver alternatives.
Current challenges include achieving uniform coverage on rough fiber surfaces and ensuring long-term stability against sweat corrosion.
Standards for electromagnetic compatibility and skin-safety testing are evolving alongside this hybrid textile-electronics field.
From fitness trackers to medical monitors, graphene fabrics blur the line between clothing and computer—soft, smart, and deeply personal.
