CONTEXT

Textile electronics offers the prospect of providing new functions to our clothes, such as wearable sensors for monitoring vital signs, sustainable energy systems or smart home interiors. The electrodes currently used do not have compatible features with textile fibers, being opaque, inflexible, fragile and not compatible with the manufacture of textiles. The present invention is intended to replace conventional electrodes facilitating the incorporation of electronic devices in textiles, by combining the conductivity of graphene to a common textile fiber.

The present graphene coating method can be used in common textile substrates, fibers or fabrics of polyethylene, polyamide, and nylon or others. The transfer process, in water and at room temperature, incorporates highly conductive and antimicrobial properties, with the mechanical and elastic properties of textile substrates unchanged, and without altering the color and transparency. The process allows the creation of conductive and antimicrobial textile substrates that can be integrated into traditional textile applications as well as in biomedical applications.

Potential applications for this technology include technical textiles and textile substrates with electronic devices, such as sensors for medical surveillance, camouflaged security devices, luminescent devices, thermoelectric devices, textile batteries, among other applications.
