Abstract
A substrate can be positioned for coating by a deposition device. The deposition device can coat the substrate with photosensitive material. The coated substrate can be positioned for exposure to light from a light source. The light source can expose a portion of the coated substrate to light to produce printed information.
Claims14
A method comprising:
- receiving a substrate at a deposition device;
- coating, using the deposition device, a graphene oxide layer onto the substrate;
- receiving the coated substrate at a light source;
- and
- printing, by at least changing an electrical property of the coated substrate based on light emitted using the light source, information onto the substrate, the printing comprising:
- adjusting a resolution of the information by adjusting a size of beams emitted by the light source;
- and
- exposing one or more areas of the coated substrate to the light from the light source according to a thickness of the graphene oxide layer coated on the substrate and a speed of moving the light source.
5 more elements
A system comprising:
- a deposition device positioned for depositing a graphene oxide layer onto a portion of a substrate when the substrate is in a coating position;
- and
- a light source configured to (i) expose, based on thickness of the graphene oxide layer coated on the substrate and a speed of moving the light source, the portion of the coated substrate comprising the graphene oxide layer to light to produce printed information and (ii) adjust a resolution of the printed information by adjusting a size of beams emitted by the light source, wherein an electrical property of the coated substrate is adjustable based on light emitted using the light source.
