Resistive switching effect has been explored in the hybrid nanocomposite of organic-inorganic materials by fabricating all printed memristive device on a flexible PET substrate. Configuration of as fabricated device is Ag/PVOH-ZnSnO3/Ag. Extremely uniform and high quality bottom Ag electrodes were deposited by reverse offset printing. Active layer of PVOH-ZnSnO3 nanocomposite was deposited by electrohydrodynamic (EHD) atomization and top Ag electrode was deposited by a non-contact printing technique of EHD patterning. Electrical and mechanical characterization showed that resistive switching characteristics of ZnSnO3 were remarkably enhanced by adding PVOH polymer in it. The fabricated device showed bipolar, nonvolatile and rewritable memory behavior at low operating voltage. A high off/on ratio, endurance and retention time of > 10(2), 500 voltage cycles and 36 h respectively were recorded without any substantial change in either HRS or LRS. The fabricated memory device showed remarkable mechanical robustness when tested against 1500 bending cycles. (C) 2016 Elsevier Ltd. All rights reserved.
