Cost-effective, mask-less, and high-throughput prototyping of flexible hybrid electronic devices using dispense printing and conductive silver ink

In this work, we demonstrate the advantages and the potentials of dispense printing (V-One, Voltera) for the realization of conductive contacts of flexible electronics. Printing parameters were optimized for Ag inks on different substrates (PCB, Si/SiO
2
and polyimide), leading to straight homogeneous printed lines with minimum feature size of
$159\pm 22\mu \mathrm{m}$
. Hybrid-manufactured Ag/InGaZnO Schottky diodes, with an average rectification ratio of 80 and an ON voltage of 0.63 V, were successfully demonstrated on flexible foils.
