Abstract

Laser-induced graphene (LIG) fabrication, while streamlined, produces amorphous structures leading to high resistivity. This paper presents a flash Joule heating (FJH) method (F-LIG) to rapidly rectify LIG's topological defects, improving conductivity fivefold and enhancing performance in soft electronics and low-voltage disinfection. A strain sensor using F-LIG/polydimethylsiloxane exhibited an 800% improvement in gauge factor compared to pristine LIG.
