A method of tuning an electrical resistance of a laser-induced graphene heater is provided. The method includes forming a base carbon heating element, and determining a target electrical resistance of a laser-induced graphene (LIG) heater to be fabricated from the base carbon heating element. The method further includes determining a targeted LIG pattern that provides the target electrical resistance, and directing laser energy on to the base carbon heating element based on the targeted LIG pattern to form one or more LIG regions. The one or more LIG regions define a LIG pattern to from the LIG heater having the target electrical resistance.
