a Image of 27 tag sensors produced on a 20 cm × 18 cm substrate using the fabrication method. Scale bar, 3 cm. b Images of fabricated patterns under ambient lighting conditions and on a uniform white background with digital contrast enhancement. Scale bar is 3 mm. c Top row shows schematic of peeling step of PVA adhesive and SEM images of the pristine AgNWs network and the network after washing away the PVA adhesive. Bottom row shows regions where the network is removed by peeling PVA adhesive, peeling with tape, and laser ablation. Scale bar is 500 nm. d Optical transmittance of the pristine AgNW network and regions where the network is removed by PVA peeling, tape peeling and laser ablation against a blank PET substrate.
