Inkjet direct printing approach for flexible electronic

Abstract

Printed flexible electronics have been extensively studied for their potential use in various applications. In this paper, a simple, low-cost, high-conductivity (0.2Ω/sq) flexible electronic circuit fabrication method is demonstrated. The commercial PET film is used as a flexible substrate, and then nanoparticle silver ink was inkjet printed on its surface, and then the flexible Ag circuit was obtained after sintering with 150 °C hot air. Although the conductance is somewhat reduced, the electronic circuits made in this way remain functional even under different folding angles or after repeated folding. The proposed development technique allows cheap, efficient, and large-scale production of flexible electronic circuits with excellent mechanical and electrical properties.
