Abstract
Electrohydrodynamic (EHD) printing technique has been deployed to fabricate flexible printed resistive (memristive) switch in a metal–insulator–metal sandwich structure of Ag/ZrO2/Ag on a polyimide substrate under normal room conditions. The top and bottom electrodes were deposited through the jetting of EHD printing and the active layer of ZrO2 between two electrodes was deposited through the atomization of EHD printing process. The achieved dimensions of the printed device were around 100μm×100μm with the thickness of the bottom electrode, switching layer and top electrode were around 230nm, 680nm and 420nm respectively. The fabricated device showed stable bipolar memristive switching behavior around ±3V. The reversible resistive switching behavior was measured with the high OFF/ON ratio of 100:1. The device kept on exhibiting memristive characteristics after being physically flexed over 500 times that shows its viability for flexible electronics applications.
