Abstract
This study demonstrates Laser-Induced Forward Transfer (LIFT) as a high-precision digital tool for fabricating components for stretchable bio-sensors. LIFT was used to print silver nanoparticle inks as fine interconnections (30-50 μm) and gold inks for graphene bio-sensor source/drain electrodes onto flexible substrates. Laser printing and subsequent sintering processes were optimized to enhance electrical conductivity while preserving substrate mechanical properties. The method produced smooth, defect-free and ultra-thin patterns with high conductivity, meeting the demands of stretchable electronics. This work highlights LIFT's significant potential for manufacturing the next generation of advanced bio-sensors and flexible electronic systems.
