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.
Claims6
A laser system comprising:
- a femtosecond laser configured to output a laser pulse with a near-infrared wavelength, 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, and
- wherein the beam delivery system is further configured to create an outline on a border of graphene electrodes by scanning the laser beam with a lower scanning speed than a reference speed, and filling up the graphene on an inside by scanning the laser beam with a high scanning speed than the reference speed.
