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.

A laser system comprising:
- 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 fabrication method of a laser-induced graphene (LIG) device, the method comprising:
- receiving a desired graphene design of a device to be patterned on wood, and
- fabricating the device patterned with graphene by using a computer-programmable scanner to directly scan a laser beam of a femtosecond laser onto the wood, based on the desired graphene design.
