Abstract: A laser system comprises a femtosecond laser, and a beam delivery system configured to deliver and scan a laser beam emanating from the femtosecond laser onto wood, based on a desired graphene design, wherein graphene is formed on the wood by the laser beam. A device capable of being fabricated by the laser system may include a temperature sensor which detects a temperature by measuring resistance of the graphene, a heater or a boiler which converts electrical energy to thermal energy, or electrical interconnects.

Abstract: A laser system includes a femtosecond laser; and a scanner configured to irradiate laser beams, which are outputted from the femtosecond laser on fabric, according to a graphene pattern. An electronic textile with graphene patterned on the fabric is manufactured by the laser beams. The graphene pattern and a structure of the fabric are differently determined depending on applications of the electronic textile.
