▎ 摘　　要

Laser-induced graphene (LIG) has endowed the assembly and integration of smart devices/structures in nextgeneration multifunctional composites with unique processing characteristics. Current LIG hybridized composites rely on precedent formation of graphene before integration process, restricting in situ structural design and performance regulation toward multi-scenario sensing applications. Here, an all-computer-aided protocol is creatively proposed with combined extrusion-printing (EP) and LIG for guaranteeing the graphene conversion on filled or pre-patterned polyimide layer, which is effective for balancing manufacturing cost and structural complexity. On the basis of unique dual-modal processing, piezoresistivity of LIG composites is optimized by a roadmap study through sequential and/or combinational control of lasing conditions, levels of pre-deformation treatment, and formats of multi-scaled fractal network. It is discovered that multi-scribing plus pre-bending with specific micro-contact structural design could regularly improve the gauge factor of LIG/composites from 0.67 to 648.8 to assure accurate strain mapping.
