Fabrication of strain gauges via contact printing: a simple route to healthcare sensors based on cross-linked gold nanoparticles
B Ketelsen, M Yesilmen, H Schlicke… - … applied materials & …, 2018 - ACS Publications
In this study, we developed a novel and efficient process for the fabrication of resistive strain
gauges for healthcare-related applications. First, 1, 9-nonanedithiol cross-linked gold
nanoparticle (GNP) films were prepared via layer-by-layer (LbL) spin-coating and
subsequently transferred onto flexible polyimide foil by contact printing. Four-point bending
tests revealed linear response characteristics with gauge factors of∼ 14 for 4 nm GNPs
and∼ 26 for 7 nm GNPs. This dependency of strain sensitivity is attributed to the …
