摘要： The invention includes methods of forming electronic circuitry on a target surface using intense pulsed light-induced mass transfer (IPLMT) of metal nanoparticles (NPs) by applying a pliable mask to a target surface, coating a carrier film with metal NPs, mounting the carrier film to the target surface and over the pliable mask so that the pliable mask is sandwiched between the target surface and the metal NPs. and exposing the metal NPs to light energy to cause atoms of the metal NPs to evaporate and transport through openings of the pliable mask and condense on the target surface, producing a conductive pattern of condensed metal on the target surface. Certain implementations may utilize a kirigami-patterned pliable mask to enhance conformity to a freeform 3D target surface. In certain implementations, zinc (Zn) may be formed by IPLMT of Zn NPs to the target surface.
