Inkjet Printed Conductive Tracks for Printed Electronics

This review briefly summarizes the recent development in fabrication of conductive tracks with inkjet printing technology. Special emphasis will be placed on material selection and printing procedures. Troubleshooting guidelines for frequent problems in inkjet printing methods, such as material selection, ink formulation, ink-substrate interaction, and post-treatment of inks, are elucidated in this article to fabricate conductive tracks or electrodes with well-defined patterns. Related applications and unsolved challenges are also briefly reviewed in this article.
