Abstract
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.

A method of tuning an electrical resistance of a laser-induced graphene heater, the method comprising:
- forming a base carbon heating element;
- determining a target electrical resistance of a laser-induced graphene (LIG) heater to be fabricated from the base carbon heating element;
- 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 at least one LIG region that defines a LIG pattern to from the LIG heater having the target electrical resistance.
A laser-induced graphene (LIG) heater comprising:
- a base carbon heating element including a first region and a second region at a different location of the base carbon heating element with respect to the first region;
- and
- LIG formed in the second region such that the second region has different electrical resistance than the first region.
